My review on 2.2.1 baseband 2.30.03 turbo sims
Over the past month I have bought and tested 3 different types of turbosims. The ones tested are (listed in order from most stable to least stable):
1.Gevey 3g plus II( china)
2.Rebel simcard (Europe)
The first sim I bought was the ismartphone. I bought a couple, some for my friends and one for myself. At first the turbosim worked great, but on the 2nd day I lost signal and the turbosim was unable to pick up signal again, and in order to regain signal I would have to put the ismarpthone into another unlocked phone... and then wait until it would regain signal (annoying as hell). I used it for another day and threw it away as it lost signal again.
The second turbosim I bought was the Gevey 3G Plus 2. When the turbosim is first put into the phone I received errors such "sim failure" and it would take a good 2-3 minutes to find a stable signal(only takes this long when you put the turbosim in for the first time). The Gevey gave me absolutely no problems for over a week, but one of my other friends said that his apn settings kept on getting wiped out (but I didn't experience this.) Every time I lost signal the phone was able to regain signal with no problems. When I powered off and then back on again, the phone would find signal almost instantly.
The most recent turbosim I bought was the rebel. I decided to give this one a try even though the Gevey was working perfectly since most people praised the rebel sim. When I first put the rebel onto the phone it was similar to the Gevey with "sim failure" and a good 2-3 minutes for a stable connection.One difference I noticed was that when the phone was powered off the rebel was unable to regain signal(I would have to toggle airplane mode on and off for it to regain signal after a power down).I tested this for a week and it was able to regain signal as long the phone was not turned off.I only tested one of the rebel turbosims so I am not 100% sure if other users experience the same problem .
