Samsung Galaxy S8 & Dual Sim/Duos

Recommended Posts

This afternoon (after doing the software update this morning), while using the phone normally it suddenly did a profile update on its own! UH OH! I read that profile updates are supposed to reset the lock back to Sprint.

 

So I rebooted the phone, popped in the AT&T SIM, and voila! It still works! Went back to Sprint, still good! 

 

So at least with the unlock method I used (some eBay guy), the phone remains unlocked after software & profile updates.

Update on using Simore/Magic-SIM to make S8 into a dual-SIM phone:

 

- My Simore adapter ribbon tore before I could use it... so never got to try it.

- Went with Magic-SIM... it is a more durable product, however, I can't get it to work. Customer service has been great at helping me trouble shoot, but the app it installs doesn't respond to anything I do... and after 1 minute of a valid connection on SIM1, it changes to say Invalid SIM. 

 

Magic-SIM has been helpful and are sending me a replacement to see if it's faulty. So after a couple weeks I should have another try (they are in England).

 

I will say that since the unlock method was a hack-job and my 2nd SIM is a FreedomPOP AT&T SIM, it's possible one or both of those are giving me issues with Magic-SIM. Perhaps if I put in a SIM directly from AT&T, T-Mobile or Verizon that it would work, I don't know. However I doubt it because directly in the phone the SIMs work and I did try a deactivated 2nd Sprint SIM and it also didn't work. So other than the adapter being faulty the only other possibility I can come up with is the way it was unlocked being incompatible with Magic-SIM. We'll see how the replacement works.

No there is a guy on eBay that unlocks it remotely for you.

Dual SIM adapters have never played nice with CDMA networks. Doubt you'll get it working tbh.

You guys watched him do it remotely, right?  What does he do?  It cannot be that hard of a process?  Is he just flashing the 'U' software?

You can't see what files he is using. You can only see that he is doing something.

That's how they keep it secret so they can continue selling it as a service.

Side note. This update definitely improved band 41 a bit. I'm getting it more than I used to but still not as much as I did with the note 5.

Ok. Does the S8 support 64 qam for upload for whenever Sprint brings that on board?

Anyone have root and use NSG on the S8?  It would show more clearly...

The answer is still no, I'm pretty sure the htc 10 on sprint supported band 13 as well.  Not sure if that was the first one though.

And what is Band 13 for? Is that the roaming frequency?

That's vzw 700 mhz.

Right... so why do we care if our Sprint phones have this?

I was just curious. Sprint also owns B13 licenses in Puerto Rico.

Same deal here. I just downloaded My Sprint since Sprint Zone never updated.
