Austria Compact 2 won't take my other t-mobile sim card?

[frankygth]

Hi,
I've tried to use my company simcard within my MDA Compact 2 but it won't work!! Any suggestions? The Compact 2 is probably simlocked but since I also use T-mobile in privat I got no idea why it doesn't work!
I got the new ROM update from T-Mobile Austria!
Please Help

Correct me if I'm wrong.

Your company is using T-mobile
You personally uses T-Mobile
You are in Austria
You used the Austria T-mobile upgrade

Right?

What is the message you see when you use your company SIM

[frankygth]

absolutly right!

The SIM says T-Mobile! The SIM Card is working fine on my company cell phone!
This is really strange! There shouldn't be any difference between privat and company contracts cause it's the same network (T-Mobile)

The Compact 2 acts like there's no SIM Card in it

... T-Mobile Austria provided a ROM update to solve some bugs!
Before I switched to the new update I tryed the company SIM - Same result!

if the sim card is old it may not be compatible with the device
it's been know to happen

[frankygth]

would it make any difference on an unlocked phone?
Or is it not possible to use this sim card at all?

[hanmin]

If the phone act as though as there is no SIM card at all, it doesn't sound like a locked phone. a locked phone will gives you various unhelpful messages. Probably as Rudegar said, in compatible SIM card. I have not heard any thing (case or solution) on SIM incompatibility. Can't help you.

one could always ask for a new sim
i've don that before my network sendt me
one right away

[frankygth]

I guess I'll try to get a new SIM!
This will probably solve the problem
Cheers, guys
