Direct answer
For the Google Pixel 10, carrier service, selected line, account activation, recipient-specific block and messaging service should be separated. First, test a normal call, SMS and another contact with Wi-Fi off.
What this covers
- Google Pixel 10 (2025 Pixel 10; confirm hardware model in Settings)
- Current Pixel family; modem, Tensor generation, biometric features and Android eligibility vary by exact model and region.
- The specific fault this record addresses: cannot make calls or send messages
What it does not cover
- ×The same symptom on a different Google product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
No usable service in the first place
What separates it No calls and no SMS, with the status bar showing no service or emergency only. Everything else on this page assumes service exists.
How to confirm Check the signal indicator and whether data works. Where there is no service at all, that is the problem to solve first.
- 2
The account is suspended or the line was ported
What separates it Emergency calls only on a phone that is otherwise perfect, often on a billing date. It looks identical to a hardware fault.
How to confirm Check the account status with the carrier before anything phone-side.
- 3
The number is blocked, or the phone is silencing unknown callers
What separates it Specific people cannot reach you, or calls go straight to voicemail without ringing. Both platforms offer silencing of unknown numbers, and block lists accumulate.
How to confirm Check the block list and any silence-unknown-callers setting. This produces a phone that appears to work perfectly and misses specific people.
- 4
Call forwarding was left on
What separates it Calls never arrive and go somewhere else entirely, often after a trip abroad or a voicemail setup. Forwarding survives until it is switched off.
How to confirm Check the call forwarding setting, which is easy to leave enabled and gives no indication that it is.
- 5
A focus mode silencing calls
What separates it Calls arrive but the phone does not ring, on a schedule. Focus and bedtime modes both do this deliberately.
How to confirm Check for an active focus mode and its allowed-callers list.
- 6
Wi-Fi calling on a poor Wi-Fi network
What separates it Calls fail or break up at home where cellular is fine, or the reverse. Wi-Fi calling prefers Wi-Fi even when the Wi-Fi is worse than the cellular signal.
How to confirm Turn Wi-Fi off and retry the same call. A clear difference identifies the path.
- 7
RCS or an internet messaging service rather than SMS
What separates it Messages fail to one person and work to everyone else, or fail on Wi-Fi and work on cellular. Modern messaging silently chooses between several transports.
How to confirm Send the same message as a plain SMS where the app allows it. Success there localises the fault to the internet transport rather than the network.
- 8
The recipient's number is stored in the wrong format
What separates it Messages fail to contacts saved without a country code, particularly after travelling or changing country.
How to confirm Compare a failing contact's stored number against the full international format.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether calls fail, messages fail, or both — and whether it is to everyone or to specific people.
- The signal indicator and whether mobile data works, which establishes whether there is service at all.
- Whether it fails on Wi-Fi, on cellular, or both.
- Whether calls ring and are missed, or never arrive at all — those are different failures.
- Whether call forwarding, a block list, or a silence-unknown-callers setting is active.
- Whether the affected contacts are stored in full international format.
- The account status with the carrier.
Establish whether there is service at all
ReversibleNo service, or emergency calls only, makes everything else on this page irrelevant. 'Emergency calls only' in particular usually means the phone found a network and was refused by it, which is an account matter rather than a phone one.
Determine whether it is everyone or specific people
ReversibleEveryone points at service, the account or a system setting. Specific people points at a block list, a contact's stored number format, or the messaging transport. These share no further steps.
Check the block list and silence-unknown-callers
ReversibleBoth produce a phone that appears to work perfectly while specific people cannot reach you, and both accumulate quietly. Calls going straight to voicemail without ringing is the classic signature.
Check call forwarding
ReversibleForwarding left on after a trip abroad or a voicemail setup sends calls somewhere else indefinitely, with no indication on the phone that it is doing so. This is a five-second check that resolves an otherwise baffling symptom.
Turn Wi-Fi off and retry the same call
ReversibleWi-Fi calling prefers Wi-Fi even when the Wi-Fi is worse than the cellular signal available. Calls that fail at home and work elsewhere, or the reverse, are identified by this single test.
Send the same message as a plain SMS
ReversibleModern messaging chooses silently between RCS, an internet service and SMS. Success as plain SMS localises the fault to the internet transport, which is a completely different investigation from the cellular network.
Check the contact's stored number format
ReversibleA number saved without a country code fails in ways that look like a network fault, particularly after travelling or changing country. Comparing a failing contact against the full international format is quick and specific.
Check for an active focus mode
ReversibleCalls that arrive without the phone ringing, on a schedule, are a focus or bedtime mode with an allowed-callers list — not a call failure. The distinction matters because nothing about the network is involved.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- 2025 Pixel 10; confirm hardware model in Settings. Current Pixel family; modem, Tensor generation, biometric features and Android eligibility vary by exact model and region.
- Display
- 6.3-inch Actua display, 20:9, 1080 x 2424 OLED at 422 PPI, Smooth Display 60–120Hz, Corning Gorilla Glass Victus 2. Note the refresh floor: this model runs 60–120Hz, not the 1–120Hz LTPO of the Pro models, so it cannot drop as low when idle — which is a real, if small, battery difference between them.
- Brightness
- Up to 2000 nits (HDR) and up to 3000 nits peak, with a contrast ratio above 2,000,000:1. Brightness is among the largest discretionary battery costs on any phone, so heavy outdoor use at peak costs real runtime here rather than indicating a fault.
- Battery
- Typical 4970mAh (minimum 4835mAh), rated by Google at 24+ hours, or up to 100 hours with Extreme Battery Saver. Compare your own runtime against that 24-hour figure and your own history rather than against a Pro model.
- Charging
- Fast charging to about 55% in around 30 minutes using a 30W USB-C PPS charger or higher, sold separately. The adapter is the variable people miss — a lower-output adapter or a laptop port falls well short of that figure, which is the usual reason charging seems far slower than advertised.
- Wireless charging
- Pixelsnap wireless charging, Qi2-certified, up to 15W. Qi2 uses magnets for alignment, so a thick case, a metal plate or a card between phone and charger defeats it entirely while cable charging carries on working.
- Memory and storage
- 128GB or 256GB, both with 12GB RAM. The RAM figure matters for one specific symptom: apps reloading from scratch when you switch back to them is memory pressure rather than crashing.
- Processor
- Google Tensor G5 with a Titan M2 security coprocessor. The chip generation is what governs how long this model keeps receiving Android and security updates.
- Cameras
- Triple rear system: 48MP Quad PD wide (ƒ/1.70, 82° field of view, 1/2" sensor), 13MP ultrawide (ƒ/2.2, 120° field of view, 1/3.1" sensor), and a 10.8MP Dual PD 5x telephoto, with Super Zoom up to 20x and optical quality at 0.6x, 1x, 5x and 10x.
- Google's own specification
- Google publishes the full specification at store.google.com/product/pixel_10_specs. Where any figure above matters to a decision, that page is the authority and this one is not.
- Symptom boundary
- This record covers Google Pixel 10 when it cannot make calls or send messages. A different symptom on the same hardware, or this symptom on a different Google product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !The account is suspended or the line has been ported away — a carrier matter that no phone-side change addresses.
- !There is no service at all and another phone on the same carrier works in the same place.
- !Calls connect and neither party can hear the other after the microphone and speaker have both been excluded.
- !Emergency calling itself is unreliable, which should be treated as urgent rather than troubleshooted at leisure.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Google Support publishes this as "Pixel and Android support". Official Pixel hardware, Android software, account and connection support. What that article does not carry is the model boundary — it is written for a product line, and 2025 Pixel 10; confirm hardware model in Settings is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
How long should the Pixel 10 battery last?+
Google rates it at 24+ hours, or up to 100 hours with Extreme Battery Saver, on a typical 4970mAh cell. Judge your runtime against that figure and your own history rather than against a Pro model, whose battery and display behave differently.
How fast does the Pixel 10 charge?+
Google rates it at about 55% in around 30 minutes, using a 30W USB-C PPS charger or higher — sold separately. The adapter is the variable people miss: a lower-output adapter or a laptop port falls well short, which is the usual explanation for charging that seems far slower than advertised.
Does the Pixel 10 support magnetic wireless charging?+
Yes — Pixelsnap wireless charging, Qi2-certified, up to 15W. Because Qi2 aligns magnetically, a thick case, a metal mount plate or a card in the case defeats it entirely, while cable charging carries on working perfectly. That is the first thing to check if wireless charging stops.
What is the Pixel 10 screen refresh rate?+
Smooth Display at 60–120Hz. Worth knowing that this is not the 1–120Hz LTPO panel used in the Pro models — it cannot drop as low when the screen is idle, which is a small but genuine difference in standby battery behaviour between the two.
How bright is the Pixel 10 screen?+
Up to 2000 nits in HDR and up to 3000 nits peak. Poor outdoor readability below that is normally the ambient light rather than a display fault — and sustained use at peak brightness is one of the largest single battery costs on the phone.
How much can the Pixel 10 zoom?+
Super Zoom up to 20x, with optical quality at 0.6x, 1x, 5x and 10x from a 10.8MP 5x telephoto. A close-up that will not focus at the long end is normally the telephoto's minimum focus distance rather than a fault — repeating the shot at 1x confirms it.
How much RAM does the Pixel 10 have?+
12GB, with either 128GB or 256GB of storage. RAM is the figure that explains apps reloading from scratch when you switch back to them — that is memory pressure rather than the apps crashing, and a restart clears it.
Calls go straight to voicemail without ringing.+
Check three things: call forwarding, the block list, and any silence-unknown-callers setting. All three produce exactly this, all three leave the phone looking perfectly healthy, and all three are easy to leave switched on without knowing.
Only one person cannot reach me.+
That rules out service, the account and the phone — all of which would affect everyone. What remains is a block list entry, that contact's stored number format, or the messaging transport being used for them specifically.
Messages fail to one contact and work to everyone else.+
Send the same message as a plain SMS if the app allows it. Modern messaging silently chooses between RCS, an internet service and SMS, and success as plain SMS localises the fault to the internet transport rather than the network. Also check that their number is stored in full international format.
Calls break up at home but are fine elsewhere.+
Turn Wi-Fi off and retry. Wi-Fi calling prefers Wi-Fi even when the Wi-Fi is worse than the cellular signal available, so a poor home network can produce worse calls than no Wi-Fi at all. One test identifies it.
My phone says emergency calls only.+
That usually means the phone found a network and was refused by it, which points at the account or the SIM rather than the radio. Check the account status with the carrier first — a suspended line and a failed radio look identical from the status bar.
Calls arrive but the phone does not ring.+
Check for an active focus mode and its allowed-callers list. Focus and bedtime modes silence calls deliberately and on a schedule, and nothing about the network or the call itself is involved.
I cannot call anyone after coming back from abroad.+
Check call forwarding first — it is commonly enabled while travelling and left on afterwards, and the phone gives no indication. Then check that the network selection has been returned to automatic rather than left on a manual foreign network.
Messages send on Wi-Fi but not on cellular.+
That points at the internet messaging transport rather than SMS. The two use completely different paths, and a transport that works on one connection and not the other is describing the network rather than the phone or the recipient.
Calls connect but nobody can hear me.+
That is a microphone problem rather than a calling one — and the first thing to check is whether a Bluetooth accessory is connected somewhere, because it takes the call's microphone with it. Record a voice note to test the microphone alone.
Does this answer apply to every Google model?+
No. It is scoped to 2025 Pixel 10; confirm hardware model in Settings. Current Pixel family; modem, Tensor generation, biometric features and Android eligibility vary by exact model and region.
What should I record before troubleshooting calls or messages?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing calls, messages. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Use another reliable path for urgent or emergency communication.
