This question is for those techies out there!
Thank you in advance.
The micro is a smaller sim card. Tmobile first started using them due to the unlocked Iphone 4's coming to our network. This didn't change the frequencies but allowed us to use a micro and eliminate our customers from having to cut their existing sims. In theory, the smaller sim allows for more space and or a larger battery. I will let the super techies give their explanation. Thanks so much for posting. Btw the lumia is the first Tmobile phone to use the the micro.
Is there a difference in the names that you could store on the micro vs regular SIM cards...?
