US T-Mobile UMA (Mobile Wifi Calling) Work?
By pnguyen7912 •
Hello,
I'm going to be moving to Qatar in the next month or so, and was wondering if anyone has any problems with UMA calling? I will be able to make and receive calls/text messages from the States and still retain my number. Does Qatar block any ports? I'll be bringing my UMA wifi router also.
Thanks,
Patrick
Update: I went ahead and brought over my T-Mobile Blackberry. UMA Works fine here even over the mobile broadband connection. There's still time when there are drop calls. I've been able to talk for an hour before the call is dropped. Older blackberries seem to work better than the newer ones. 2 of my co-workers have newer Blackberries and sometimes there are issues with the WIFI connection. A reboot usually fixes the issue. I went ahead and brought over a T-Mobile @Home wireless router and set it up to give preferred bandwidth to the blackberry. No noticeable difference with a regular wireless router.
