I bought a YESSIM from a local guy and it was the black 3G "new" sim solution supposively made for the iphone but it stopped working after a few days. My question is which sim soln worked best for a sustained amount of time (atleast a week) on Tmobile's network?

I have been using a universal-sim for 3 months now on T-Mobile US.

Everything works great. Calls, SMS, GPS, Edge...

Only problem is I have to restart the phone every no and then if it losses signal. Its rare but it happens, But after a restart its fine. Its probably because Im using an old version v5.00. I think there are newer versions out that solve the lost signal issue.

Just google universal-sim.

having to turn off your phone like that is not necessary my friend

purchase one of my sim solutions and you will see that the i-smartphone sim CONSTANTLY searches for a signal using different cellphone towers so you are constantly receiving a strong signal... therefore very unlikely you will lose signal in the first place!

I have a "Gevey Plus" that I bought off of eBay (U.S.A.) for ~ $10 and it is going strong in Japan. 3G even works (with apn settings manually installed.)

Edit:
Here is a picture of the official Gevey Plus. Make sure when you buy it, the seller has this image.

let's hope it doesn't stop working in a week (like the old Geveys)

i have to admit i-smartphone sim works pretty well in chicago using t-mobile... only on a few occasion i dropped signal and edge is gone, need to reboot the phone (tried on numerous times, same route, same driving speed, same time; happens randomly, so far 2 out of 20 times as of now)

You need to calm down with your comments. I realized you were a seller here before I posted this but wanted some other feedback from people.

I read a post about someone that bought one of your sim cards and it got stuck in their phone. This is not what Im looking for.

If you were smart you would quit running in circles trying to promote your product and instead let the people that used it talk for themselves....which they already have in a negative way.

You definitely misread what the guy posted about his sim unlock getting stuck (don't even know which of the 3 models of i-smartphone? maybe 2nd gen)... for one, I did not sell him it, and secondly, I am selling and using the latest model... 0.09MM thick..

I move between Canada (home) and UK and need to change SIMs often, never have I had problems with this device failing and whatnot. I am just giving you an opinion about what product works best.

Matey above me even says the i-smartphone works well in Chicago with the same network, EDGE working perfectly and very small signal loss, especially while roaming (10% of times, during drive?)

please, speak when you have experience or at least read other people's post correctly.

Speaking from experience, I said I'd stop moderating this section but I'm getting a little bit annoyed by your repeated self promotion in each post.

If you have some cra^H^H^H solution to sell, the flea market section is there for you. Please refrain from constant advertising in each post.

And yeah, enjoy your sales until 2.2 is out
