I've been running a standard 2degrees SIM in my Samsung Galaxy Note 2 LTE [GT-N7105] for a few months now with no problems.
The other day I ordered a Touch2Pay SIM off the 2D website to play around with the Snapper services.
After activating the SIM it worked fine for around 3 hours before it stopped allowing any voice calls however 3G data still worked fine.
Thinking it was a SIM problem I ordered another Touch2Pay SIM however the same thing happened.
I tried both Touch2Pay SIMs in a Galaxy S2 and get the same issue however my old non-Touch2Pay SIM works fine.
I was under the impression that even through the Touch2Pay service may not be officially supported by my phone model, the SIM card should at least operate as a normal SIM in incompatible phones?
