What about if I currently have the Nexus 4 on T-Mobile's $30 plan and just want a new micro SIM card to use with a Nexus 5?
Do I get the card for free from T-Mobile and LTE is naturally included? Or do I have to try to sign up all over again (which might be hard to do since these $30 deals are typically only for new customers)?
I had a Samsung GIO device on the $30 plan when I switched to the Nexus5.
I bought the MicroSim from the Tmo store.
I started a Chat on My-Tmobile
I told the Chat tech I wanted to switch devices, keep the same plan and phone number.
I gave the new MicroSim Serial Number over Chat to the Support person.
I Powered off the Nexus5 and installed the MicroSim.
I powered up the Nexus5.
I received the WELCOME TO TMobile text within about 1 minute on the Nexus5 and kept the same phone number. (The Chat Tech said it could take up to 2 hours - haha.
PS, Update on my stock Android Email problem not signing-in to my @sbcglobal email account using POP3 or IMAP incoming servers when on LTE. If I disable SETTINGS > IMAP > SYNC for each account, I can manually refresh mail on LTE network with no problems.
Thanks to an independent mailapp developer forum who claims he found a bug in Google source code that affects all mail apps.

View topic - No new mail notification for IMAP
Correction/Update - Manual refresh occasionally fails with the sign-in problem also. :-(
