No Service On Um Sim

Ukap · 12-07-2006, 17:44

I have been back in the USA one month & leave again for a trip to Europe.
I plan to use UM and Callback world again. I have the same UM Sim which worked well last month.

Turned on my phone today & it displays "No service" Anyone know the reason why?
I have emailed United Mobile but have not received a reply.

When I went in Mexico it got connection overnight (after a couple of hours still no signal - the morning after signal). Let the UM sim think a bit about it... you never know.

It may be a network thing. Call the number and see what message you get.

Tried calling the number - goes straight through to our UM voicemail. The phone did not ring. Still showing "No Service"
It never did this before!!!

Are you sure all the settings are correct (i.e. if ou use a triband phone, you are on the right frequency?). Sorry for this silly suggestion, but it did happen before to other people who worte on this forum.

Tried that. I haven't altered any settings. All I did when I returned from my trip was to turn it off. It has been off for one month. Worked perfectly then.

Don't know your phone model...basically in the USA um roams on either T Mobile or Cingular....it is not registering on whichever one it is set to.

Check yourmanual to manually select your roaming carrier...maybe t mobile is not registering but cingular is or vice versa.

You should borrow a friend's GSM phone (850/1900 at least) to see if the UM SIM works with it. That way you can narrow the problem down to either the SIM or the phone. Good luck.

My SIM registers as usaul on Cingy here in VA. Balance works OK, too.

If another SIM works in the phone and it registers on a US network, it is not the phone.
Can you search available networks?

I guess sometimes SIM cards go bad -- maybe the are magnetized or something happens to then.

Best of luck. Annoying, not doubt.

Did you perhaps reach the automatic deactivation time on your UM SIM? I can't find it right now, but it seems to me UM requires you use the card at least once every 9 months. If you've used CBW exclusively during that time, it's possible that you haven't actually spent any of the time on the card- which would trigger deactivation per your user agreement. Just a thought.
