Hi. Just received the ultrasim from Unlocked Cellular.

It has the corner ic chip mount. I trimmed my T-Mobile and it is a very good fit. When I inserted it first, the sim holder in the I-Phone would not close. I did not want to risk forcing it in place. I pulled to ultra-sim-tmobile combo out, pushed everything nice and flat and snug into the holder, thinking it might be just a tad bit out of whack and tried it again. At that point, I had a difficult time just starting the combo into the slot. I pulled it out and noticed at the bottom of the ultrasim that it was slightly curling up on the bottom left side (underneath the cut off corner portion). I had some additional double sided small tape provided with the sim chip so I ensured the bottom is firmly taped to the tmobile sim.

I smoothed it out and out and out, and then tried again. I got it again almost all the way down but not all the way to where I can close the sim card holder into place.

Any ideas? I have tried to contact Unlocked cellular but there is no one available for assistance.

Thank you. So damn close!!

My issue is fixed. I ended up taking some sandpaper and using it on the back of my T-Mobile sim chip to make it thinner. That with a bit a tape on the bottom to keep the ultra sim from curling up when being inserted allowed me to insert the sim card.

I did have a lot of issues still with getting the card in the last tiny bit. There, I had to use just a touch of force to get the holder all the way into the phone.

I turned it on, and it did a quick search and BOOM- up pops T-Mobile.

So yeah! The Ultra sim works!

Have a good day!

Michael

btw, we did speak with the buyer and that sandpaper trick is good to know
we did many phones before and this is the first time we actually heard about the curling ... anyway all is good

thanks for feedback

Hello, I am in the same position you were in. I had trouble installing my ultrasim from unlocked cellular and when I did it read "no sim installed" I am trying your advice with the sandpaper and will see if that works, it just seems like such a tight fight. Any suggestions on troubleshooting? Dying to get this up and running. Iphone is jailbroken, any other tips? THANK YOU!

How you used the tape on the card?

small tiny bit of tape to hold card in place, not placed on the metal parts

Thanks Amassey .

Have ultrasim and no luck with it in unlocking iphone OOB 1.1.2. Have tried everything with this card, phone jailbroken and when I install ultrasim with my sim it reads "no sim installed" BUMMER. ANYONE with info PLEASE HELP. Is there something I need to update on my phone? It is jailbroken and activated!

which country are you from?
i think you have to install "iWorld" for international phones (outside USA).
let me know if it worked and how. thanks.

Dear Amassey,

How is the fit? The Ultrasim layed over the sim card perfectly for me at the very beginning. I was lucky with the cut.

for the tightness, PROCEED WITH CAUTION, I took a bit of rough sandpaper, since it was giving me a fit trying to insert everything together, and I slowly sanded the back of the original sim card. I got to the point to just where I could start to see the back of the sim circuity showing through. I then ensured it was even all around, protecting the Ultrasim very carefully.

When I was done, the combo unit was a tad bit thinner than the original Sim card itself.

I also want to mention that the Ultrasim has to fit exactly over the original sim card. I have a newer T-Mobile sim card and I could see the three contacts from the Ultra sim lay perfectly on top of the other sim. There was some double sided and very thin tape included with the Ultra sim. I used all the tape and made sure that everything lay as flat as possible! That is the key to success! Perfect alignment and very flat.

The only reason I used tape (Scoth tape from the dispensor) on the bottom was due to such a tight fit, the Ultra sim kept getting caught and curling up. Taping it around the bottom (not touching any of the contact points on the front) to the back help it slide right in!

Don't give up on this. It will work! Also, the support from Unlocked Cellular was very quick.

Keep us on the loop!

Michael

Week 47 jailbroken working like a champ on T-Mobile with an Ultra sim!
