So, let me start off by saying I do have the "unofficial" gevey supreme that came in the yellow packaging. I also know that even though it says "without any operation" you still have to go through all the steps you would with a regular gevey sim to get it working with tmobile. Here's my story: I get rather poor service in parts of my house. I was on the official Gevey sim when it first came out (for iphone 4 that is). The original one; it would require you to turn off your phone, dial 112, etc EVERY time you lose service. Since I frequently visit the areas in my house where I don't get service, it got rather irritating to reset it EVEY single time. So, I ordered the Gevey Supreme Pro Plus in Yellow off Ebay. That was just over a month ago. When I got it, I put it in, accepted the welcome message, dialed 112, hung up, toggled airplane mode on/off and BOOM! I had service. If I lost service, it would come right on back. It was great. About a week after having it (and constantly losing service but getting it back in a snap (gevey was flawless)) I visited my cabin where I get no service. I forgot my charger, so I turn off my phone. The next day, I turned it back on when I got home and service came back! Just like gevey supreme was supposed to do. However, I lost service a few hours later and it never came back. i turned it off and was greeted with the welcome menu again, so I went through the unlock process again. It worked for a while and then I lost it again. So i toggled airplane mode and would get "searching" and "no service". I even took out the sim, waited a bit, and reinserted it, followed the procedure and after playing with it for several hours, I finally got it to work again - if I lost service, it would come back. Now, three weeks later, it did it again. However, I've been fiddling with it for 3 days now, and I can never get it to show service unless I manually do the procedure over and over again. From what I can tell, I can't find anyone who has had this problem on here or tmobile forums (And yes, I've consulted google lol). I've tried dialing 112, *112, *000. I saw a video that said, after the first time of dialing 112 and getting service, you must immediately reboot the phone, which I did (and service did come back but as soon as I hit a dead spot in my house, it disappeared and hasn't come back). I read that because Gevey uses TMSI spoofing, it's a good idea to put your sim back in a phone that gives you a legitimate TMSI number - so I stuck my sim in my old iphone 3g which is SoftUnlocked using the Dev Teams magic - got service, took out my sim, put it back in the i4, did the unlock process, got service but after a while, I lost it again and, of course, it didn't come back. When I lose service, I have toggled airplane mode and I will get "Searching" but to no avail. So, I end up turning it off, and doing the whole accept, wait 15 sec, dial 112, toggle airplane, and then I get service. Quick details, I have an i4 on 4.3.3 with BB 2.10.04. Data roaming is enabled (I have even turned it off to see what would happen), 3g is off. Under settings > general > about, it says carrier is 10.0 (but I currently have no service and haven't reset it..again). I have TMO USA in Washington. Does anyone have any suggestions for me? Any help is much appreciated, and yes, I know that Gevey ultra is out, but I don't want to buy yet another gevey sim.
