Uma for 9900?

[rnh2112]

I was on the phone with a CS from t-mobile just a couple days ago and she said 7.1 is available as a download from them... I told her i didn't see the 7.1 download on their website, and she said that if i upgraded to the 9900 she would show me where to get the 7.1 download, but unfortunately even with my full discount available it's still too expensive at this point in time for me to afford, lol

I've had my BB Bold 9900 now for about a week. I've installed the latest OS 7.1 build v7.1.0.74 on the Blackberry. It will execute WiFi/UMA calling. However, it will not transition from WiFi Calling to broadband at all. It will drop your call. The phone will give you a warning that you are loosing an effective signal as you get close to the transceiver limits.

It is certainly a less capable system than the BB Bold 9700 with regard to UMA calling.

Yep, that's a shame it doesn't transition properly, hopefully in the not too distant future os7.2, or whichever they will call it will be released that will address this issue.

I fear not for I think they are going to WiFi calling which is like UMA but fails to do handoffs. Its quality may also not be as good but better than nothing.

I don't think the 9900 will ever be able to transition between broadband and WiFi. I hope I'm wrong here because I already miss the feature that my 9700 had.

Is there a specific app needed to run UMA? I am running 7.1.0.74. I cannot make a UMA call on WIFI. What am I missing?

There is no specific app for UMA on blackberry. However, your carrier must support the service. In the U.S. only t-mobile supports UMA and wifi calling.

No they have not released an official 7.1 and they aren't saying when.

If you are with tMobile and want to have UMA like calling, just install one of the 7.1 OS. It works great. I have not had a single problem with using it. In fact I'd rather be on a WiFi call.

[dagerlach]

I think I spoke to soon. My WiFi calling works just fine once you have a call going. However, after I finish a call, making another call seems to fail most of the time. If I turn off and then turn on both transceivers it will work for another call. I'm not sure what is screwed up.... I am debating moving to the next OS version.

UMA calling, which allows for an in-call handoff between WiFi and cell service, is a hardware feature not built into the 8910 (Torch) or 9900 (Bold). It is found in the T-Mobile USA branded 8320, 8520, 8900, 9300, 9360, 9700, & 9780*.

Instead a similar service called WiFi Calling will be included in a 7.1 updates for the T-Mobile USA branded 8910 (Torch) & 9900 (Bold). This is a software feature and will not (cannot) allow for in-call handoffs between WiFi and cell service. Instead a call will be disconnected and must be re-called when moving between WiFi Calling and cellular service.

Furthermore to take advantage of the new WiFi Calling it appears the account may require a E911 address be registered with T-Mobile USA before the WiFi Calling service will be enabled. If this is true or not will only be known when T-Mobile USA officially releases (and thus supports) the 7.1 updates for their devices, apparently Real Soon Now.

*There are handsets from other carriers that also support UMA calling but they are hardcoded to those carrier's UMA servers and thus will not easily work on T-Mobile's network.
