Call Back Service

[Ukap]

I have United Mobile sim and will be traveling to Europe. I plan to use callbackworld for all outgoing & incoming calls. My clients have my 1800 + pin number from callbackworld which will reach me on my cell phone. I have tried it out & it works fine.

However - I see UM uses the callback system also.
UM rate - 0.39 Callback 0.14

When I dial out using callbackworld I have a 909 callback number to call, hang up and then I receive a callback & then dial any number.
How I do I know that my callback is coming from callbackworld and not UM?

When you dial your callback #, the first callback is from UM. You answer that and the allow the phone to ring once. Then you hang up. The second callback is then from CBW or your callback service. Since your first callback did not result in a completed connection, you are not charged for that. The second callback is with CBW and when your party answers, OR BEFORE, your connect time begins with CBW.

If you dial a # directly, say +49 171 123456, you are called back and when you answer, the phone @ your destination number +49 171 123456 rings. When they answer, you are connected and your are charged for the outgoing setup and per minute fees by UM.

Hope this helps.

I am messing up real bad. I am eating through my UMobile minutes while testing this thing out!! This is the 1st time I have used this.

My cell phone has a LiechtensteinUM # but I want to use a USA callback 909 number.

So from my UM cell phone I dial 01-909-xxx-xxxx. I then get my call cannot go through message & hang up the phone.

It then calls me back - who is calling me back - l UM or Callbackworld?

It then called me back a second time & I did not know which line I was using.

Any tips please......

As Snaimon posted above, The first callback is UM. As long as you have the UM sim in that phone, the first call back is always going to be from UM. When you hear the first callback(UM has called the number you were trying to reach, your 909#), you answer, you will hear it ring, then hangup (no charges yet). The next callback will be from CBW (they have called your number), you will hear it ring, once they answer, charges start with CBW.

If you make the mistake if calling your destination# first, you will receive a callback from UM only, when you answer you will hear your destination# ring, once they answer your charges with UM will start. plus the .25 euro connection charge.

Wow! testing it from here (USA) will cost you a lot since incoming calls are not free here. I used mine extensively on a recent cruise, and CBW+UM worked flawlessly!

To be precise you should dial +1909 a number in the international format...

[snaimon]

You are eating up your minutes because inbound in NOT FREE in the US. I think the cost to receive is 99 or 79 e-cents. In most EU countries, inbound is free.

It works, believe me. Don't do any more testing while you are in the US. Don't answer any more calls HERE. Don't call voicemail here using the phone. Don't do call divert here in US using the phone.

when I am calling the USA from Greece, Turkey, Italy or UK
I dial 1 909?

I thought I had to dial the country code first & should dial 01 909 or 001 909

I will be in a European country, calling from a Liectenstein cell number to a USA number.

ON THE MOBILE PHONE....

IMO dial + 1 (for US). The + takes the place of 011 or 001. Dial +49 for calls to Germany from the mobile. This should always work from any mobile anywhere.

ONCE YOU ARE CONNECTED TO CBW, use the instructions you received. If I recall correctly, just the country code in all cases.

If you want to "practice," set up your T-MO number or landline as a callback # and practice with that # rather than the UM.

If you are in Europe dial 00-1-909... to call a US number. Dial 00-49-... to call a German number, etc.

I don't know what to dial in the US as I've never used my Riiing phone here

The idea of the + sign preceding the country code is that you don't have to care what is a local "exit code" for international calls: 00, 011 or whatever else. "+CountryCode" works (ot at least it should) in GSM networks for all national and international calls and SMS sending to "regular" numbers. This "standarised format" of the number is valid in "normal" roaming as well. The existence of such a common number format does not exclude using local formats. I guess that's why 00CountryCode works in UM - simply it's an "international exit code" in Liechtenstein and all the Liechtenstein-based callbacks may work with 00 just like they do with +.
