Problem solved but questions

[pete_c]

My Kaiser has been working fine now for about a year. Recently traveled from one city to another. When I got off the plane noticed that I couldn't dial out nor surf the web. I also noticed that the touch screen was pretty unresponsive. While driving home from the airport and playing with my phone (about 30 minutes or so) shut off the 3G part of the phone and noticed that I could dial out. The phone was in Edge mode and it somewhat worked but the touchscreen was still kind of unresponsive. Called and opened a service request with AT&T. After a couple of calls and some "detail" checking I was told that my SIM was trashed. They said that maybe it was trashed going thru the airport X-Ray machine. (odd to me). Wondering if somehow there was an attempt to hijack my SIM remotely (BT?) or am I being paranoid? I recieved a new SIM today and I had it turned on. All appears well at this time.

I had the same issue with my old Sonyericsson. Traveling from Indianapolis to Denver, when I arrived the messaging and internet was really buggy. They told me that my sim card wasn't compatible with their network. That seemed really odd to me too. However, they gave me a new one and once it was registered on the network everything was cool.

Long story short - I don't think anybody was trying to hack your phone via bluetooth or anything like that. There are just minor quirks in the network when traveling long distances... probably from the network being made up of smaller ones that were simply acquired through buy-outs.

Traveling long distances will not "trash" your SIM, I go to HKG every year...no problems...that is a farther distance than Indianapolis to Denver...

Nobody said anything about the distance itself causing issues. What I said was that not all areas of att's networks are up to par, so older sim's may not work everywhere.

I don't work for att or anything but this has been my experience.

Thanks all for your responses. My 3G is still working in the Midwest. BTW my SIM card was working fine for almost a year (when I purchased Tilt). I also have traveled to the same place in FL a "few" times this past year with no SIM issues. One thing though is that 3G is not available yet where I travel to FL. (everytime I go there I can only get the Edge network).

It's funny... I've been on 3 round-trip flights since buying my Tilt. After each flight, the phone started acting buggy. Laggy, screen not refreshing when it should, programs refusing to run, etc.

A hard reset and restoring from my latest backup resolved all the issues each time. So, it seems that (at least in my case) the SD card is fine, but memory may be getting trashed in the phone. Of course, I'm blaming it on the x-ray process.

Next time I fly, I plan to turn the phone off completely before going thru screening to see if that makes a difference. Anyone else notice odd things happening after a plane trip?

I had a similar problem in the UK, although didn't actually involve travelling!

When I got my new Kaiser through O2 UK, I had upgraded from my old Wizard. I swapped SIM's and everything was fine. 3G was in operation in my part of the world at the time and it worked spot-on.

Then, after 2 weeks, 3G suddenly stopped working. GPRS was OK (no EDGE here!) but just couldn't get 3G signal. On startup, the 3G icon would appear, the signal strength would then drop to nothing, and would then change to a 'G'.

O2 said that my SIM was not 3G compatible - strange how it was working before though! They sent me a new SIM and everything's been fine since.

What I believe happened in my case is that they had upgraded the network in my area to HSDPA but hadn't activated it at that time. I believe the changeover is what made my older SIM suddenly incompatible.

HSDPA became active about 3 days after receiving my new SIM and my signal etc. has been fine ever since.

So, possibly when you guys have travelled, you've actually visited places where the network has been upgraded making your SIM incompatible there?

Also, have you tried manually searching for networks? If you're in a foreign country, your phone may be continually scanning for networks which will undoubtedly slow it down and make the screen unresponsive?
