The Same Problem
I have the same problem with my ZP990. Can you please write how you solved the problem?
Thanks.
Hi.OK.... I found a solution!
I now have excellent signal on both SIMs, and very fast data on the one I use for 3G.
Pressed for time right now, and this is an old thread. If anyone else lost cellular (GSM/CDMA/3G) reception, let me know and I'll write how to solve it.
