Hi guys, my iphone 3g 2.1 was using an ismart card since I got the phone, and it worked for about 2 months until now, it has the No sim error. I just place an order for a grevey, is that good? Because Virgin sim is more expensive...

Gevey sim works perfect for me.

The Gevey-3G sim works perfectly for me on T-Mobile USA. I rarely get signal loss, but it comes back right away.

No.

Not for most people atleast.

It doesnt work at all for me. No SIM error right from the start.

when I used gevey sim, itune showed it didn't recognize sim card
and I cannot sync my iphone.

My experience...

I tried 2 Gevey Sim..
The first one didn't work right out of the box on my new 3G phone. so then I got a new Gevey; inserted right in.. and voila it works.. no problems at all. Its being more than 2 months now.
some caviats:
1. Cannot enable 3G on the phone. (works on edge only)
2. If you switch to airplane mode & back, the signal is lost and needs the phone to be restarted.
3. Data roaming has to be enabled even though u are within network/area. I am not sure if this is for the Gevey OR true for data access in general.

Hope I helped.

I just got a Gevey today and it's been working all day.No lost signal or lost service.


Running on 8gb 3G 2.1 Firmware. Tmobile USA

I got two different geveys, first one, sometime work sometime not, 2nd one work perfectly. It is different (the packaging very similiar) between them ( the chip/sim), I suspect the 1st one is fake.

I've been using the Gevey sim for over a month and so far it has been very smooth. No problems with edge and with the epc.tmobile.com proxy I can use edge on youtube. I've also used the Gevey sim on about 10 of my customer's phones and they haven't come back to complain.

I use one and like it very much. no lost signal or any other issues. I think it depends on your location,carrier and sim card. I am reading different reviews all over about sim adapters.
