EE and tampnet

[Angus39]

Currently working offshore North Sea in UK sector , and trying to use the Tampnet network .   No data or texts will come through?  Is there a setting that needs to be changed?  I have roaming switched on , using Iphone 12.   The phone shows full signal bar and 4g but no data in or out .     Tampnet say that EE is a roaming partner

Once roaming is enabled, then unless you specifically request it cancelled, it remains active. The welcome text message can only arrive by virtue of being connected to a mobile network - thus roaming is proven.

That can only leave a local/roaming network issue, or interworking between Tampnet & EE.

As for the question of which country you're in, all mobile networks globally use an MCC/MNC (Mobile country code/Mobile Network Code) to uniquely identify themselves. A quick Google suggests Tampnet use a variety, which would be consistent with operating across multiple regions. Only if they use a 234-MCC could they be classed as UK-based.

Any suggestion for a solution?

Being offshore I appreciate troubleshooting is limited - do other users on the same network have any issues? I presume Tampnet have a monopoly on coverage there, but if not - try selecting alternative MNOs in your phone's manual network search mode.

Contacting EE CS to have an investigation raised, is your ultimate next course - You can either contact +44 7953 966150 from another working phone, or +44 800 0798586 using a web-calling app such as Skype over WiFi.
