Can't Access Digital Voice app

portlandboy — Tue, 03 Sep 2024 15:11:00 GMT

I've been using the TT Digital Voice app for quite a while without any issues.

This week a call was diverted from the landline, but only rang on my wife's phone, not on mine.

I tried to login to the app and it no longer allows me to access it. A message box appears stating:

Invalid SIM

Your account only supports SIM cards approved by Talk Talk Telecom Group PLC.

However, my wife and myself both use the same SIM cards (Spuzu) operating on the EE network, and have the same Samsung handsets. Her TT Digital Voice still works fine for incoming and outgoing diverts via the landline.

I've already

Uninstalled the app,
Updated my phone OS,
Turned the phone,off and back on,
Reinstalled the Digital Voice app.,

None of this has had any effect on my ability to login to the app. The same message still prevents me getting to the Login page.

Any ideas of a fix please?

I think that this app is being discontinued.

I am now receiving the exactly same error after applying the latest Android update. We are paying for this service, so TalkTalk would need to supply another method of using the digital landline from our mobile phone - surely!

I looked at my SIM details on the phone in more detail, and it appeared that the SIMs were not being recognised by the phone after the update! I restarted the phone, the SIM is now seen and Digital Voice is happy again. It was a phone issue all along!
