ID Mobile Data Not Working on Samsung Phones in the UK

When mobile data suddenly stops working on a Samsung phone using ID Mobile in the UK, the issue is rarely random. Despite signal bars showing and calls working normally, mobile internet can fail due to very specific network–device interactions. This article takes a Type A approach: direct, experience-led, and practical — without sugar-coating weak assumptions.

ID Mobile runs on the Three UK network, and that detail matters more than most people realise. Samsung devices, especially after updates or SIM changes, are sensitive to how Three-based MVNOs handle data provisioning. If your data has stopped working, there are a few structural causes you must confront first.

First Reality Check: Signal Bars Do Not Equal Working Data

One of the most common wrong assumptions is believing that signal strength guarantees mobile internet. On ID Mobile, it does not.

Your phone can show 4G or 5G while data remains unusable because:

  • Data authentication is blocked at the network level
  • The APN profile is incomplete or outdated
  • The SIM is attached to the mast but not authorised for data

If calls and texts work but apps don’t load, you are not dealing with a hardware fault.

Samsung-Specific Issue: Automatic APN Provisioning Fails Quietly

Samsung phones rely heavily on automatic carrier configuration. When this fails on ID Mobile, the phone often stays silent — no error messages, no warnings.

This commonly happens:

  • After a Samsung One UI update
  • When switching SIMs between phones
  • When moving from another Three-based network

The phone appears connected, but mobile data never fully establishes. Users often waste time restarting the device repeatedly, which rarely helps.

Why Network Mode Switching Usually Makes Things Worse

A typical reaction is toggling between 5G, 4G-only, and auto modes. On ID Mobile, this behaviour often resets the data session before it can complete.

Samsung’s radio stack tries to renegotiate each time — and if you interrupt it repeatedly, you delay recovery. If you’ve already done this multiple times, stop.

SIM Age and Compatibility Are Underestimated Problems

Older ID Mobile SIMs can still handle calls and texts but fail with modern LTE and 5G data authentication. Samsung phones are less forgiving of outdated SIM profiles than some other brands.

If your SIM:

  • Is several years old
  • Was issued before widespread 5G rollout
  • Has been moved across multiple phones

Then mobile data failure is not surprising. No amount of settings changes will fix a SIM that the network no longer fully supports.

Do Not Rush Into a Factory Reset

Factory resets are overused and misunderstood. They do not re-authorise your SIM on the ID Mobile network.

In fact, a reset can:

  • Erase useful carrier configuration data
  • Remove cached provisioning states
  • Force the phone into another failed auto-setup cycle

Unless support explicitly instructs you to reset, it is usually a waste of time.

APN Editing: Only Useful If You Know the Exact Failure

Manually editing APN settings is often suggested online — and just as often done incorrectly.

On Samsung phones, even one incorrect APN field can silently block data. Worse, ID Mobile may overwrite your changes later during background provisioning.

If you don’t know exactly which value is wrong, blind APN edits are not a smart first move.

Why the Problem Often Appears After an Update

Samsung updates can refresh the network stack. When this happens, the phone re-requests carrier profiles. If ID Mobile’s profile does not deploy cleanly, data can fail while voice remains intact.

This explains why:

  • Data worked yesterday but not today
  • No physical change triggered the issue
  • Only mobile data is affected

It feels sudden — but the cause is technical, not mysterious.

When ID Mobile Support Is Actually Necessary

There are situations where self-troubleshooting stops being productive. You should contact ID Mobile if:

  • Your SIM is recognised but data never connects
  • You’ve ruled out device damage
  • The issue persists across locations

Support can check provisioning status and SIM eligibility — things you cannot verify on the phone itself.

What Experienced Users Learn the Hard Way

People who’ve dealt with repeated ID Mobile data issues on Samsung devices learn one lesson quickly: random troubleshooting wastes time.

The real fixes usually involve:

  • Correct carrier provisioning
  • SIM replacement when necessary
  • Letting the network complete its validation process

Not endless toggling, resetting, or guessing.

Final Perspective

If ID Mobile data is not working on your Samsung phone in the UK, the cause is almost never “just bad signal”. It is usually a mismatch between SIM, carrier configuration, and Samsung’s network handling.

Understanding that saves hours of frustration. AvNexo’s UK mobile analysis consistently shows that calm, structured diagnosis beats panic-based fixes — especially on MVNO networks like ID Mobile.
