I purchased a Nokia 206, now i'm facing with a when i want to use both sim cards problem !
most of the time the second sim is not working (shows zero signal) until i restart the phone !
when i restart my phone, after that both sim will work for some short time...
what's the solution way ??
Presumably you have tried swapping SIM 1 and SIM 2 in their respective slots and device elicits the same behaviour? Is one SIM much older than the other?
