Absolute garbage. In fact, TMUS is one of the few major carriers to implement trusted porting which is one of the easiest ways to target a number used in 2FA.

I understood my post just fine. What aspects of it are you having difficulty with?

2FA?!

Or you could speak in a language that people in the forum can understand.

2FA = Two factor authentication - the requirement that when you login you need a password (something you know) and some other piece of information based on something you have (a phone, an app on a phone), usually a multi digit code that is used once. Getting the code via a text message is a common method, along with various security applications and secure devices. Good video that explains it much better than me!

The problem with using text message is if someone is able to "steal" you phone number, a problem that has been proved possible and not unique to t-mobile. Good reddit thread about that happening to a t-mobile customer. And another one that happened to a AT&T customer. I am sure there are plenty more out there for all the providers, they are all based on the same method, tricking a support person into porting your phone number to a new SIM.
A good article on why not to use SMS for second factor authentication (2FA) with you accounts, but you should still use 2FA but using a different method!

We use T-Mobile. Our particular location has slightly spotty service due to nearby hills and tower placement (eg none in Griffith Park). T-Mobile has provided us with a house signal booster for no charge while we have their service.

T-Mobile is great on international data. It is unlimited albeit at 2G.

I use T-Mobile. 3 lines for $145. One line has international calling/texting.
You could check out https://ting.com/ which is a T-Mobile mvno and much cheaper.
Google voice number for 2 factor authentication and/or international calls

Would you like me to Google layman explanations for you also?

I forgot they gave us a booster too. We also live in a hilly area. The free international data was great whilst son was travelling around EU on his own in the summer enabling him to use google and fb/WhatsApp to call us.

SueZ_1

Did they? Are you sure it wasn't a femtocell? I'm pretty sure it was a femtocell, given the boosters are junk.

SueZ_1

If you're going to use a TMUS MVNO use MetroPCS.

petitefrancaise

No idea. They gave us a solution.

Do you plug the device into your LAN?

BTW - 3 lines for $145 (even including international calling - have you not heard of Google Voice or SIP? You're throwing your money away with it) is a terrible deal. Why didn't you jump on the variety of free line promos they've run the last couple of years, or the 20% hook up codes offered?
