what firmware and patch count and mcc-mnc is your yessim using? and what firmware is your 3g using? 2.0 or 2.01?

Also are you jailbroken or still factory?

Thanks

then it must have come with a yesup. Put the yessim in the yesup and read the info that it shows it will tell you the firmware patch count and mccmnc

Then let me know

Well, why lose signal? very simple, every time when u lose signals on your iphone, iphone is trying to reconnect to your provider signal , your provider will automatic send a certification for the service. and some how iphone with sim adaptor cant not retrieve that certification. That’s why you have to plug the sim card back to a tmobile or original provider phone to retrieve that certification before u can get your provider back.

I RECENTLY PUT MY PATCH COUNT AT 15, BETA 4 FW, IPHONE 2.0.1, UNIVERSAL. EDGE WORKS FINE AND REGAINS SERVICE WHEN IT LOSES IT.

Never used to do that when I had it at 30 or 1 PC. Hope this helps.

I have had the same problems with yessim.. doesnt work for me

Guys I tried all sorts and they ALL failed. I then found this one Home*-*Any Network - iPhone 3g unlocking And its been in now for 8 weeks and never failed once. I travel about 3000miles a month and have never taken it out once. It just changes cells as and when without problem. I'm on Vodafone in the UK if that helps. John

i tried i-smartphone sim and yessim for a couple of days. Signal was dropping a lot.
Then Pascal helped me out, and my 3G has been working eversince. Signal never drops, 3G and GPS is working fine. Im definately happy with this solution!
The video here show the sim:

Hi guys. Thanks for the video showing how to use the unlock sim card. I was not sure how to do it. I bought the unlock sim card from iPhone Sim Unlock - 3G iPHONE UNLOCKING SOLUTION
So far I had excellent signal (no lose of it), SMS GPS and of course 3G.
