Hola,

Have 4 lines with Tmobile for 18 years ( I know - I won't get squat free lol) and 2 of those lines are with my kids. They are heading to London, the Paris, then Rome. We can't seem to find a good answer, but here goes...😁

Assuming you’re on a recent postpaid plan.

1. Can the 2 phones overseas call each other? 

Yes; 25¢/min but they can also use a VoIP app like Skype, Viber or Facetime and it will be free.

2. Is Texting free between all 4 lines, even if 2 are overseas?

Sí.

3. Can I call those 2 phones from the US without taking a 2nd mortgage on my home?

Again 25¢/min. Again VoIP will be free. Calls to the USA will be free if WiFi Calling is used but phones have a pernicious way of picking the wrong mode whenever possible. Sort of a corollary to Murphy's Law.

4. Is there a better option when they get over to the UK, France and Paris like getting a Trac phone or other, so calls won't be $ 3.00 a minute

The best option would be to use a VoIP app to make calls and use text a lot. If your kids normally receive a lot of incoming calls from random folks, if might be best to have them just set all incoming calls to unconditionally forward to voicemail. Use Visual Voicemail app to retrieve messages. And call back when the phone is locked onto WiFi Calling  The biggest thing is understanding how roaming is billed and exercising self discipline. I don't know what you mean by "Kids" but that term is not generally synonymous with "self discipline".  

I'm told that T-Mobile fixed the issue with unanswered calls being charged when roaming but I still don't trust it. One big issue is that if you are making a call to a non-US number while abroad, you nunca want to use WiFi Calling, unless you have the Stateside-International option. WiFi Calling is billed as though you are in the USA and T-Mobile's rack international rates are outrageous.
