I had a pretty hard time SIM swapping. After removing the t-Mobile SIM and re-insert my Net10 ATT SIM, Cellular Data Network had disappeared before I could get back. I could do this on iOS 6 with little effort. I changed my technique. I now entered Cellular Data Network with the T-Mobile SIM in the iPhone while the status bar showing Searching… I removed the T-Mobile SIM, and re-inserted my NEt10 AT&T SIM before the iPhone would recognize that the SIM was removed. This took me between 6-12 attempts. Finally, I got my iPhone to recognize my Net10 AT&T SIM while I still on the Cellular Data Network page for the T-Mobile SIM. At this point, I entered my APN values. there was another problem, the iPhone would keep changing my Data APN, MMS APN, and MMS Proxy Values back to the incorrect ATT values. I had to reenter them another 5 to 6 times before I had all the values correct. I tapped Cellular and to go back up a level in Settings.
This was the second time, I was able to do this. It was much easier than the first time, but no where as easy as it wad for me with iOS 7.
I had to SIM swap again after restoring my iPhone back up. I wanted to see if I could do it a second time. It took a number of tries. But I got it to work after a half dozen times.
I finally got it to work. I had to remain in Cellular Data Network after putting the T-Mobile SIM in, and then SIM swap. I did this many times. I finally was able to get it to work.
Sill not able to SIM swap. After iPhone reset, the iPhone doesn’t recognize shows No SIM after swapping SIMs…
I have not successfully SIM swapped yet. When I put the Net10 SIM back in the phone I can’t get to Cellular Data Network. I did manage at one point to stay in Cellular Data Network by entering with the T-Mobile SIM in and very quickly swapping in my Net10 SIM. The iPhone recognized the Net10 SIM and populated the ATT values over the T-Mobile ones. The problem was as I edited the values, it kept changing them back.
I am doing an restore iPhone from iTunes and I am going to try with a fresh install….
I tried the SIM swap this morning. So far I have been able to see the Cellular Data Network settings when putting the T-Mobile SIM in. It disappears after I put my Net10 SIM back in… So far, I am NOT able to SIM swap. I am still working on it.
I did the iOS 7 on my iPhone 5. It worked. I had the Net10 APN profile installed. The profile remained after the upgrade. My data is working fine. I don’t know if you will need to sim swap again if you used that method. I’ll be testing that later tonight.
I can also confirm, that the Cellular Data Network option is still hidden in iOS 7 with my Net 10 wireless ATT compatible SIM card installed.
I am installing as I write this. I will let you know how it goes.
