Can you please educate your tech support staff. I had a question about HSPA++ vs LTE . When I asked the technician about HSPA or + or ++ they acted like I was speaking a foreign language and and I had to explain it to them. You have had LTE for about a year. Your technicians should
have some knowledge of HSPA because all of your phones a year or older are non-LTE.
I was also told by your customer service agent that if my daughter wants to keep from getting roaming charges in Mexico she should use WiFi calling and turn Airplane mode on so there is no cellular roaming charges. _I will let that sink in for a minute_. I love TMO but misinforming customers or not having the knowledge to support legacy hardware (non-LET, which is not all legacy, you sell many non-lte phones) is not the way to win/retain customers.
