Iphone 4s Sprint R Sim Air problem - GSM-Forum

I bought this R sim and when I put in 4s Sprint, select carrier menu pop ups, I select US Sprint then it goes to Accept, no choose 4s/5s window comes up. Is it really r sim air 2? Will it work with 4s Sprint? Thanks

RSIM Air(first version) is better for 4S than RSIM Air2. It has two modes(Mode2 for 3G data with 128K SIMs, Mode3 for outgoing SMS outside the USA). I think Mode3 also works within the USA better than Mode2 for 128K SIMs. Users report not receiving calls or texts sometimes in Mode2. Mode3 deletes Sprint bundle/replaces it with Carrier bundle/vf nl bundle, which seems to resolve the loss of texts and calls. This is a recurring issue on 5/5S that cannot be jailbroken.
