No Service

[hinds]

I had no problems with my local gsm carrier which operats on 1800Mhz band until a new carrier arrived in the market operating on 850/1900 (not yet launched but testing). Now very often I only see the 850/1900 carrier, to which I obviously cannot connect, and I cannot see my carrier for long periods in certain locations. My phone then shows, "No service".

At these "no service' times everyone around my is able to see my carrier on their handsets. I have also experienced a version of this in roaming also but it's real problem at home. Seems like the radio searches for 850 or 1900 first and if it finds any a network it stops searching.

Friends with Treo 850s had the same problem but there were able to choose a preferred band. I also recently heard of other users of Windows 2003 devices in my area having the same problems on non-imate handsets.

I have read about newer radio versions like 1.13 and 1.15 but it is not clear to me if there address this problem at all. I also saw a band switching tool but that was for the Wallaby ROM. Has anyone experienced this problem and if so what can I do?

My software stack on my phone is the latest imate PDA2K releases:
ROM version: 1.40.00 WWE
Radio version: 1.12.00
ExtROM version: 1.40.176 WWE

What happens when you do a network search? You might want to try setting your network selection to manual as well since it seems that the new GSM 850/1900 (according to GSMWorld.com it is Digicel) network is causing some kind of reception issues for you.

You are correct about where the interference is coming from. I have tried using manual but my phone begins searching, gives me the option of selecting Digicel (850/1900) but my carrier (1800) is not shown.
