Recently bough a UM sim card and had no problems calling into my +423.663 number while in Canada using an Allstream LD calling card.

I'm currently in France on business and my colleagues in Canada are having trouble reaching me with the same Allstream LD card. They have even tried another carrier and is getting the same message: "We're Sorry, your call will not go through. Will you please hang up and try again. This is a recording... 6045"

I also tested this by calling from a land line (in France) using the same calling card and I got the same recording!! I can't even call into UM's customer service #(+423.663.09.99.11) with this calling card since it ends with the same message.

Checking prepaid balance or dialing out works. I just can't receive any incoming calls from canada using Allstream! I talked to Allstream's customer service but they tell me the problem is not on their end.

I've even tried manually switching to another wireless provider (Orange F, BYTEL, F SFR) but all of them are giving me the same result. However, my colleague was able to call me on many occasions directly using his mobile in Italy.

Who is restricting these incoming calls? Is it the French mobile operators or is it UM??

I suspect the problem lies with the calling card. Because rates to call +423 mobile numbers are generally higher this probably forces some of them to bar this destinacion.

If you want I can ring you from here. ...

This is strange since I suspect the calling card company would be very glad to pass on the full charges to its customer. I was able to use the same calling card to call into my UM number while I was in Canada. Not sure why it wouldn't work in France.

Thanks for the offer to call me but I already know it works from certain countries.
I'm guessing the problem lies with either the French mobile providers or UM's roaming agreement. Maybe both...

In the past (haven't been there since January) I have had difficulties getting callbackworld to work in France....don't really know if the French mobile companies are doing anything to sabotage UM.

If someone can call you (your friend you mentioned) then UM works fine. If only you cannot be called from Canada then it is probably their fault ;)

That is why I offered to call you. If I also did then it would lead us to the conclusion that the service works fine and that you should be looking elsewhere!

I understand but why am I able to call my UM mobile in Canada using the same calling card? I am dialing the Lichenstein number so the same charge applies.

Maybe when you return you will see if the situation has changed...

I would say the issue is with the calling card (CC). It initially worked because it's the first time someone is using that calling card to call a FL number. The CC company may have not been charging calls to FL mobiles appropriately and they may have ceased completing calls once they found that out, till they put the appropriate charges in place. The calling card I use here in the states to call FL mobiles completes 40% of the time. Calling directly from any phone completes 100% of the time.

In response to Bossman and his 40% completion rate. Carriers often have a number of pathes to complete a call. If path 1 doesn't work, go to path 2. For a cheap rate to a Lichtenstein mobile, they might have only one path.

I constantly am looking for cheap routes to Lichtenstein, but I think that eventually all routes will get closed down. Moving the route to the UK or Germany might make some sense if their termination costs are similar to the domestic providers.

Hi guys. I've been having the same problem with my United Mobile SIM card. I tested it while I was in Italy and Switzerland recently and it worked perfectly (friends in Europe were able to get through and I was able to call). A colleague in the US told me that she couldn't get through, though. Well, now that I'm back in the US, I'm not able to call my United Mobile either. (I was trying from my home line.)

Anyone have any updated news re: this problem? I'm very concerned about it since my new company, Zengo Wireless (zengowireless.com), primarily sells these types of SIM cards. United Mobile has seemed wonderful since I've been working with them, so I hope they fix this problem soon. I'm planning on calling when they're customer service line opens to figure out what's going on. I'll let you know if they say anything useful.
