Ive been trying to read the posts on the best sim adapter but I feel like the more I read the more Im getting confused...
I just want to hear about the sim adapters that people have found to work
how long have they been working
how much did it cost
what network are you on
ease of setup and such
Of course if you want to give input on ones to absolutly stay away from then thats ok

please dont post unless you have actually tried one and have some input.(If you absolutly have to ask a question to someone, send them a PM or something)
I dont want this thread cluttered by requests and questions, just straight up results from the people that have used the sim adapters. Thank you
Im on US T-Mobile network and am looking for a good solution

Here's a clue..if your in the United States, none of them work.

your best option would be universal sim or yessim. All the other ones might work ok or partially, the edge doesn't work in most of them or sms doesn't work, but yessim and universal sim (with latest update should work fine). That's just my personal opinion based on experience. Be aware that you might damage the sim tray, or even your iphone if you don't follow instructions.

That's incorrect.

Some do work, but they seem to be limited to weeks before failing. Although a few newer chips claim to have the ability to update, to keep them working.

I'm using universal sim right now. Updated to v5.40. I'm in California with Tmobile. Only been using it for 24h

Signal is good. Turn off and on pick up fast!
Driving around the city for 6 hours and didn't lose signal!
Tzone hack work. But must turn on data roaming!
Gps work, but must turn on 3g in setting to get exact location (the dot)
Incoming call, out going, SMS in and out works great!
iPhone 3g pick up Tmobile signal better than 1st gen iPhone.

I'm happy for now!
Btw I'm on 2.0.2 pwned with jailbreak and activation! Root size set to 1000mb!

u can buy this universal sim from some of the resellers on their website! Make sure u askthem to update the sim to the latest software, or else it won't work! Those sellers are lazy as $&@$. If u want it to keep working, u have to buy a pkey updater for $30. The sim is $20

Can you let is know if it loses the signal at any point? These cards usually work in the beginning but stop once you move basestations
Thanks a lot

I've tried a Turbo Sim and it doesn't work here in Massachusetts on T-Mobile.

it has been over 48hours and still work great! Like I said, I drove around the city for 6 hours and never lost signal (I delivery pizza). My house has very weak Tmobile signal. I'm not able to pick up signal in my kitchen with my old 2g iPhone. But now, I can almost have signal any place I stand in my kitchen, and able to make and receive calls!

If it lost signal, it will pick up signal again when u go to a place that has signal!

One thing I notice is that if some how I lose signal in a place I know that there is tmobile signal, I just make a call, and immediately I got signal back! Kinda weird...

Tzone hack work great with this thing. It's a big plus!

great news so far! Please keep us posted. I'm really anxious to purchase something to get my 3G iPhone working on tmobile. And I too use the tzones hack on my 2G so knowing it works on the 3G is great!

[istorm]

update! No need to turn on 3G feature to get exact location in map!

I think the phone get better signal with 3G turn off too, even though tmobile don't have 3g, but turn it off make the phone focus more on cell signal more I think!

I think the 3g use more battery than old iPhone! Especially using gps! Battery goes FAST...

[istorm]

still loving it! Almost a week already! Everything is fine!
