How to change Bandmode / Frequency

If I go into the "Mobile Network Engineering Screens" menu and then into "Cell Information..." the bandmode is set to "GSM850" which is causing me to get SOS. How do I change the bandmode to GSM900? I've tried clicking on GSM800 and selecting "All" but when I back to the menu and then back into Cell Information it changes back to GSM850.

Re: How to change Bandmode / Frequency

You would have to get a different Blackberry phone.  One that will work to that specific network.  Two Blackberry phones, GSM, same model, may look the same, but have different frequencies because of the network carrier.

Re: How to change Bandmode / Frequency

I do believe that my phone support this because I've checked the specifications on the Blackberry website and It says It does support GSM900 so I think it's just a case of changing the settings. I dont see why a shop would sell a phone that cant support the UK Band Freqeuncy?
