No data coverage

My 4G/internet is not working once I enter any building that isn’t covered by WiFi. I have sufficient data allowance in my package, however it is not letting me use the internet when I am off WiFi. Outdoors is ok but one bar/No Service inside any building. I bought three sims for three different handsets and all three are having the same issue. All three handsets have been through the recommended steps - toggle airplane mode/switch phone off & on again etc and nothing has made a difference

Hi @ams321.

Thank you for your post. I’m sorry to hear that you’re experiencing no network coverage in several areas, including your work postcode LS1 4AG. I understand how frustrating this must be, especially as you had no issues with your previous provider in the same building.

I’ve carried out a coverage check for the LS1 4AG area, and the map shows some congestion today. Network congestion occurs when a network is handling more data traffic than it can comfortably manage at once. This “backup” of data requests happens when too many calls, texts, and data sessions are made in the same area at the same time, which can affect signal and data performance.

To help revive your connectivity, could you please try the following steps:

Restart your device to refresh your connection to the network.
Turn Airplane Mode on for around 30 seconds, then turn it off again.
Check that your mobile data is switched on (if you’re experiencing data issues).
Remove your SIM card, gently wipe it with a clean, dry cloth, reinsert it, and restart your device.
Check that your device software is fully up to date.

If you’re still experiencing issues after trying these steps, please contact our Live Chat team directly via: https://www.idmobile.co.uk/live-chat so that they can assess more closely.

Hi @ams321,

Thank you for reaching out, and I'm sorry to hear you're experiencing problems with your mobile data indoors. I understand how frustrating this must be, especially as you've tested three different SIMs and handsets and are experiencing the same issue.

As you've already completed the basic troubleshooting, please try the following additional checks:

Set all three handsets to 4G only, as 4G can provide a more stable connection than 5G in some locations.
Check that mobile data is enabled and that your iD Mobile SIM is selected as the preferred SIM for mobile data.
Turn Wi-Fi off completely and check whether the handset shows 4G/LTE when inside the building.
Check Data Saver/Low Data Mode and make sure it isn't restricting mobile data.
Reset the network settings on the affected handset. Please note that this can remove saved Wi-Fi passwords and Bluetooth connections.
If your handset supports it, manually select the iD Mobile/Three network by switching off Automatic Network Selection, allowing the available networks to load, and selecting the appropriate network. You can then switch automatic selection back on after testing.
If possible, test the service near a window and further inside the building. This can help establish whether the issue is related to indoor signal penetration.

As all three SIMs are experiencing the same issue across different handsets, this may indicate that the problem is related to the network coverage in the buildings you're visiting rather than the SIMs or handsets themselves.

If the issue continues after trying the above, please contact us via Live Chat so we can check the coverage for the specific locations and investigate this further with you.

I have done all of the above except reset network settings, as not prepared to lose passwords for a problem that didn’t exist before I used this SIM.
Two of us have worked in the same building for six years with no data issues whatsoever prior to joining ID mobile so I don’t accept that there’s an issue with coverage in the building

Hi @ams321.

Thanks for confirming what you’ve already tried, and I understand you’re not comfortable doing a network reset if it could affect saved passwords.

To be certain about coverage in your building, could you please share your full postcode

Thanks,

There are several postcodes and areas where I have no network coverage. My work postcode is LS1 4AG. Please do not tell me it’s the building that has the issue - I had zero issues for six years with my previous provider in the same building
