Hello. I have a 13 year old cell phone with a 13 year old Vodafone prepaid (mini) SIM card. Have been working perfectly all the time, and of course it is on 2G/GSM.
A couple of weeks ago I acquired a new mobile which uses micro SIM. So I did a SIM swap.
The new SIM works fine on 3G, but not on 2G/GSM. I always get "no service" if I choose 2G/GSM. I put the new SIM back on the 13 old 2G phone and same thing, no service.
I am very keen on getting the 2G/GSM connection as eventually I want to use a dual SIM phone, with secondary SIM on GSM.
Wondering if anyone has seen this before?
