Hi there

Thanks for the response. I don’t really know what a VPN or APN is, sorry. I did reset all the network settings though, without success.

Interestingly, I’m at work now - I took out the sim, and gave it a wipe, then popped it back in - and I got a (weak) connection for a minute or two (i.e. not enough to stream anything, but better than nothing - and more than I’ve ever had at work for months), but then I completely lost the connection again.

Is it possible the SIM is at fault, and that a replacement would sort this issue?

Thanks again

Hi ​@DRH80, 

Thanks for the detailed update that actually helps narrow things down quite a bit.

Based on what you’ve described (brief signal after reseating the SIM, followed by complete loss again, and ongoing weak/unstable connectivity), there could be:

• Local/network or device-related limitation

However, it’s also important to note:

If the signal is consistently weak in your work location, it may be coverage or indoor building shielding
If the issue is happening in multiple locations, it could still be SIM-related, but we’d also consider device/network settings or a line issue

What I’d recommend next (in order)
1. Try the SIM in another unlocked phone (if available)
2. If the issue persists → request a replacement SIM
3. If it improves in another device → likely handset-related
4. If it fails everywhere → we investigate the SIM/line more closely

Hi there - Thanks for the response. I’ve now tried the SIM in another phone, and the problem persists. No signal at all. Moving on to option 2 - how do I go about getting a new SIM?

Hi ​@DRH80.

Thanks for testing the SIM in another phone, that’s really helpful.

For a replacement SIM, you have two options:

You can pick one up free of charge from your nearest Currys store
Or you can contact us directly via Live Chat and we can arrange to have one delivered to your home within 2 working days

You can reach us here: https://www.idmobile.co.uk/live-chat.

Once you’ve got the new SIM, we can help make sure everything is set up correctly for you.

Thanks,

Hi there

I got a replacement SIM and have now activated it. Unfortunately, the problem is just the same. I’m at work, the phone is showing full bars of 4G, but absolutely no mobile data connection available. Same situation at home when I switched the WiFi off to test it.

I can see that my work location is in an area marked on the ID coverage map as Excellent 4G Coverage for both Indoors and Outdoors although no 5G availability.

The strange thing is that the 4G used to work well (i.e. I could stream videos) but now doesn’t work at all.

Are there any additional steps I can take? I am out of contract so will leave ID unless I can actually use the products I’m paying for.

Hi ​@DRH80 ,

Can you advise the make and model of the phone you are using please to provide additional troubleshooting steps.

To me, it looks like deliberate network throttling when it's busy... It's the same in CW2. In the early morning hours, mobile data works perfectly, but later it drops to absurdly low speeds or doesn't work at all. Switching to airplane mode and back solves the problem for a few seconds to a few minutes. It's a joke, not funny at all. It's a good thing I have a flexible contract with you and I'll be canceling in a few days.

Hi Marquerita

I followed these steps, but it is still the same I’m afraid. I can’t even connect enough to send a WhatsApp message, the connection is basically non-existent, even though the phone is still showing full bars 4G.

It seems to me that the problem is with weak signal both at work and at home, since messages start to come through at a certain point on my way home. But it’s quite a long way from my workplace. Similarly, signal drops again completely when I get a few streets away from home, always at roughly the same spot.

Two things are particularly annoying about this - firstly, even though neither place has 5G, both places show excellent 4G indoors and outdoors on the iD coverage map. Secondly, it used to work really well - I could always connect at work, well enough to stream videos, but now - absolutely nothing.

Please can you advise on the next steps?
