Hi, I have a blacklisted iph 5 on T Mobile USA. I ordered a R-Sim 8+ (supported by ios7). I tried to insert a Orange France sim card and I got service only for a few seconds. Then it says no service. I pulled out the sim card and wait a bit and I got service which does not last long. Did this happen to someone with other networks? Anyone can advise about a solution? Is it my Sim card on this French network? unfortunately I do not have a nano sim card on other networks to test. Also the cut micro to nano sim card does not fit with Gevey R-Sim card. It is too big. Thanks.
