I don't stream movies on my small phone because I have a large TV and surround sound for that so it works for me.

The customer service is beyond terrible!

They are completely incompetent. I have spent hours and the phone with them for things that would have taken minutes to do with Verizon. I have added up about 20 hours on the phone with them so far this week because they have to keep transferring me from department to department. They are actually dumb and it is astonishing. I don't know if this is their training program or if they literally just higher anyone. Any time they dont feel like helping they just hang up or leave you on eternal hold so that you have to call back again. The line is always busy so you have to wait 30 min to an hour to get to someone. They are horrible, it is making realize the money savings is not worth the headache and I will just switch back to Verizon.

Horrible customer service -- worst experience ever

Xfinity Mobile is great as long as

1. you never need support

2. never move to a location without local service

3. don't try to bring your device with you

I switched my service on Dec 10th but spent the 4.5 days online/on the phone trying to unlock my phone. Complete runaround through their phone and chat support. Endless circles waiting in bottomless queues.

Finally resolved my problem after only 5 minutes with the correct person in "Unlocking Department". BTW who has an entire department dedicated to just unlocking phones?!? The support "executive" I spoke with had no clue as to the hassle I encountered just trying to reach a real live person. I begged her not to drop the call until my phone was unlocked. As it turned out, it only too her less than 10 SECONDS to unlock the phone. Literally a mouse click and it was done.
