[Q] APN settings with non-T-Mobile SIM cards - manual or automatic?
Hey all, a (hopefully) quick question here. I have the T-Mobile branded HTC One. Obviously, it came with a T-Mobile micro SIM, and the T-Mobile APN settings already on it.
I had the phone unlocked (by T-Mobile, under their international travelers unlock policy) over the summer, and I used it in Scandinavia on both Tre Sweden and Saunalahti in Finland with prepaid micro SIM cards (that I bought in stores there). It worked perfectly fine, with full HSPA+ speeds - I was really thrilled.
I did run into one minor annoyance, though: my wife has an AT&T-branded Galaxy S III (unlocked by AT&T under their unlock policy, and which she now uses on our T-Mobile account). When she put the Tre Sweden or Saunalahti prepaid micro SIM cards into her GS3, her GS3 automatically read the APN settings off of the SIM cards, and updated the APN settings on her phone - so she was able to use data immediately with no tinkering.
However, on my HTC One, when I put in the prepaid micro SIM cards from the foreign wireless carriers, the APN settings did not automatically update: I had to read them off of my wife's GS3 and manually enter them into my One. Obviously, this wasn't a huge deal - it only took a couple of minutes each time. But it's certainly conceivable that I will be traveling on my own in the future, and not have her GS3 to read the APN settings from.
So, is there any setting I'm missing, or any way to have the T-Mobile-branded HTC One automatically update the APN settings when a new SIM card is inserted? Or does that always have to be done manually on the One? If so, that's a pain - why does it automatically work on the GS3, but not on the One?
Thanks in advance!
