Apple iPhone 14 Plus has no cellular service or data

6.7-inch all-screen OLED, at 2778-by-1284 at 458 ppi. That matters more than it sounds — a procedure written for a different size in the same line puts controls in different places, and gestures that depend on reach behave differently.

Lightning. A USB-C cable will not fit at all, which is the usual explanation when a charger that works on a newer iPhone in the same household does nothing here. Lightning cables also fail internally at the strain point, so a cable swap is the first test for slow or intermittent charging.

Face ID. It is deliberately quick to refuse when not confident, which is why darkness, strong backlight, unusual angles and lying down all reduce it — and why a case lip or a screen protector over the sensor area disables it entirely.

The A15 Bionic. This determines how long the model keeps getting iOS updates, and it is the reason an app can drop support for this iPhone while running fine on a newer one — a support-window matter rather than a fault to troubleshoot.

128GB/256GB/512GB. Before assuming capacity is the problem, read the storage breakdown: photos and video are usually the dominant category, and a full recently-deleted album is the most common reason deleting appears to free nothing at all.

No — water resistant, rated IP68, which Apple specifies as a maximum depth of 6 metres for up to 30 minutes under IEC standard 60529. That is a laboratory figure for a new device in fresh water; it degrades with age, drops and seal disturbance, and liquid damage is not warranted.

Yes — Dual eSIM, with two active eSIMs and storage for eight or more profiles. Note that the default line for calls, for messages and for cellular data are three separate settings, and crossing them produces calls on one number while data or messages use another.

Wi-Fi 6 (802.11ax) with 2x2 MIMO. That is worth knowing before blaming the phone for slower Wi-Fi than a newer device on the same network — a router running a newer standard falls back to what the phone supports rather than refusing it, so the difference is specification rather than fault.

Bluetooth 5.3. Version affects range, reconnection behaviour and which accessory features are available. A newer accessory paired here operates at this version's capabilities rather than failing, which is regularly mistaken for a pairing fault when the accessory simply cannot do everything it does on a newer phone.

800 nits maximum brightness (typical), with 1200 nits peak (HDR). Brightness is among the largest single consumers of battery, so outdoor use at full brightness costs real runtime — and poor outdoor readability on this model is usually this figure rather than a display fault.

Apple rates it at up to 15W over MagSafe. Wattage differs across this line, so a charger that fast-charges a newer iPhone may deliver less here — and if wireless charging has stopped while cable charging works, take the case off first, because a metal plate or a card defeats the alignment entirely.

Apple rates it at up to 50% charge in around 30 minutes. That assumes an adequate adapter — a low-output adapter, a laptop USB port or an old car charger falls well short, and that is the usual reason a phone charges far more slowly than the specification suggests.

Usually that the phone has found a network and been refused by it — which points at the account or the SIM rather than at the radio. Check the account status with the carrier before doing anything to the phone; a suspended line and a failed radio look identical from the status bar.

Compare with another phone on the same carrier, same place, same time. Both struggling is coverage and nothing on your phone will change it. Only yours struggling narrows it to the phone, the SIM or the account — and the SIM-swap test separates those three definitively.

If you use an eSIM, that is the first thing to check. An eSIM does not travel with the handset the way a plastic SIM does — it has to be transferred or reissued, and a phone swap, a reset or a repair can leave the profile behind entirely.

That split is diagnostic: the radio and the account are both fine, because calls prove them. What remains is carrier settings and the APN. Check for a carrier settings update rather than editing the APN by hand, which is easy to get wrong and hard to reverse.

Only against the carrier's own published values, and only after checking for a carrier settings update. A hand-edited APN that is slightly wrong produces a phone that half works, and it is much harder to diagnose afterwards than the original problem.

Check which line is set as the default for cellular data — it is a separate setting from the default voice line. Two-line phones make this easy to get wrong and give almost no indication that it is wrong.

Compare it against another phone on the same carrier there. If both are poor, that is coverage — and Wi-Fi calling is the practical answer rather than anything on the phone. Building construction matters a lot here: foil-backed insulation and low-emissivity glazing both attenuate heavily.

Check the carrier-lock status in the phone's own settings. A handset locked to another carrier will show no service with a new SIM regardless of configuration, and only the original carrier can unlock it.

Where the problem is genuinely weak coverage at a fixed address, yes. Where the problem is the account, the SIM or a manual network selection, no — and those are cheaper to exclude first. Establish that another phone on the same carrier is equally poor before spending anything.

No. It is scoped to A2632/A2885/A2886/A2887/A2888. Apple iPhone family; connector, modem, camera, biometric and iOS eligibility vary by exact model.

Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.

A reset can erase accounts, networks, maps, schedules or preferences without distinguishing no service, cellular data. The ordered checks preserve that evidence.

Use the most reliable available path for emergency calls; do not delete the only eSIM without a replacement plan.
