I’ve just read up some about this and I cant find anything saying iPhone supports this. It must just be a bug on the t-mobile GAN where you’re roaming.
Can you find any UMA settings when you are on UMA? is this consistent any time your wifi is on? Do you have it jailbroken? Where can we get some diagnostics info about the UMA?
Another question, do you by chance have a Femtocell from O2? The thing you plug into your router to emit a signal?
Sorry for my ignorance. Whats UMA?
Pat i did’nt see mobile flickr is it free
Pat i know your with me on this but i need to get it off my chest anyway. My sister lives in England and is looking at buying an iPhone and as i already have the new one she rang me for some advice. I went onto the 02 website and looked at the Tariffs …. i am so angry …. why oh why do we continue to be ripped off in this small Island of ours …..
Look for yourself

Looks to me like O2 has one of their network identification settings set incorrectly. UMA/GAN has never been claimed for iPhone. Are you sure this is not a 3G failover to an EDGE situation in reality?
In fact, looking further at the positioning of the “UMA” lettering, it is at the position where my iPhone identifies my carrier (in my case I see ROGERS in this position).
guys UMA is not a software i work in the nokia Nseries department and i know that no matter how much you try to build a software to have a UMA on the phone you just cant do it its like you having a EURO 3g phone and trying to use it in the AT&T 3G it just doesnt work it doesnt have that radio, do you get the point UMA is not a software it is a special hardware like we have in our 6301 there are 3 version of 6301 and only one support UMA why coz it has that radio on it, so there is no way of getting a UMA on iphone unless Apple it self builds that radio and start putting on their next generation Iphone.
I work in the UMA technology. It allows any WiFi capable handset to make calls through the internet. Basically the phone should have a wifi connection and then there should be a third party app on iphone that can utilize the wifi connection to make calls through internet. But dont confuse this with VoIP calls. This a different kind of VoIP as in you are still using the cellular providers network but you get access through your nearest available WiFi connection.
Prashant: Your 2/11 post is fascinating. That’s the only time I’ve seen anyone say that we might be able to use our new iPhone to make UMA calls on our T-Mobile@home network here in our home. (We get crappy reception with all of the cell phone carriers; we’ve tried every one.) Can you please e-mail me directly to let me know if there is an app we can download for the iPhone to accomplish this magic. Thanks.
I went to the states and came back to japan and now my iphone says UMA instead of Softbank… the softbank guys didnt even know what was up.
I don’t think you are runnning UMA. When a UMA phone switches over, the GSM bars go away and they are replaced with another sort of strength meter. Some UMA phones show pink dots for the strength, and other don’t show the strength level other than a lower case or upper case UMA. The fact that it is still showing the GSM strength indicator means you are probably still on GSM.
UMA is a HARDWARE feature. if a phone doesn’t have it when it’s made, it will never have it.
UMA is NOT free calls.
UMA is very very simple. If a device has UMA and it can’t get a normal 800/900/1800Mhz signal from a cell tower but it is connected Via WiFi it will attempt to establish an IPSEC VPN connection to the carrier instead. If the VPN connects (routers and firewall permitting), then the phone just sends all it’s normal GSM, UMTS (calls, texts etc..) protocols over the VPN instead of by 900/1800Mhz radio.
THE CALLS ARE STILL BILLED AS NORMAL THEY ARE NOT FREE!!
The service is free to use though because it is good for the carier if you can use your device where you normally couldn’t.
Lmfao that’s not uma, that’s make it mine. It’s an app you can get from cydia if you have a jailbroken iPhone. You can get it to say anything u want in place of the carrier. Wow this noob went through all this trouble to fool us. Why? To serve what purpose? BTW UMA IS HARDWARE NOT SOFTWARE!!! That’s means no app can use uma since it’s not built in the iPhone. Since I already see that some posts go into great detail as to what uma is and how it works I’m not going to tire my thumbs. iPhone keyboard is annoying: ( but I do agree uma on iPhone is a great idea. Hope to see it soon.
While UMA relies on specific hardware (most commonly an 802.11 radio), this hardware is already present in all iPhones. However, the iPhone currently uses the 802.11 radio only for data access.
In theory, that makes UMA a software issue on the iPhone hardware. To date, it appears that Apple has not implemented UMA. Perhaps it will come in a future release. Apple doesn’t have much reason to do so, as their carrier partner in the US (AT&T) doesn’t have UMA infrastructure. T-Mobile does in the US, to support their HotSpot@Home and associated T-Mobile@Home services, but apparently not in Germany, where they are the exclusive iPhone supplier.
