Sim won't work in basic phone

[PheonaL_2290897]

I have a basic handset, with no Internet connection (think original Nokia style). I have got a smarty sim and it won't recognise it. So I got a new basic phone - still won't recognise it. I've ordered a new sim... same problem.  Does anyone know why it won't work? The phones are unlocked.

What phone do you have, is it 3g or have 4g also ?

Your phone would need to be at least 3G capable to work with a SMARTY SIM @PheonaL_2290897.

And from 2025 onwards, your phone would need to be at least 4G capable.

Perhaps some basic handsets don't have 3G capability.

old basic phones normally use 2G, smarty, which runs on the three network does not have 2G because three has never had a 2G network
