Hey guys. I just got the iPhone 12 from TMobile and traded it with my old iPhone 6. The iphone 12 came with a sim card but for some reason i switched out the sim cards without calling tmobile and now i have the old sim card in my iphone 12. The iphone 12 can make calls and stuff but ive noticed that the network speeds are still relatively slow. Im thinking because the old sim doesn’t really have 5G capabilities and i will need to switch the sims again to allow 5G on the iphone 12. A problem is that Ive already sent my phone back to tmobile and dont know how i can get that sim card back. Any ideas? do I just request another sim card and then call tmobile or is it possible they can do somethign with my current sim card in my iphone 12 and upgrade it somehow? Alsom in my cellular settings on my iphoen 12, it says i have a cellular plan of “4GB til 2/28/19 then 2.5GB” but under usage in the cellular settings it says ive used 100 mb out of unlimited data that i apparantly have…It also says i only have 4GB of high speed data on my tmobile dashboard to use. Is there some mistake with the 4GB/2.5GB part or something? Thanks!
