Do I have to Top Up - can't I just pay as I go?
Using this particular service you have to Top Up in advance, however Advent Dial offers a cheap pay as you go service for international calls.

How do I top up?
Top-up directly from your mobile - Text us the message ADVENT to the short number 83006. This text will cost you £3 and we will credit your mobile phone with £3 of call credit.

Making the Call from your mobile
After topping-up you can make international calls from your mobile any time you want. All you have to do is dial one of the access numbers - 020 7124 6666 is probably best (read on for details) - followed by your international number in full - remember not to press your send or call button again after you have dialed the international number.

The access numbers your can use are 020 7124 6666 or 0800 594 6666 or 0845 451 6666.

Which access number should I  use?
The answer to this will depend on which mobile network you are with and the specific tariff plan that your network has you contracted to. For instance - if you have bundled free minutes with your network then the 0207 number may be the best to use. Or - if your network allows you to dial 0800 numbers for free (many charge for a standard national rate call) then the 0800 number may suit you best.

To get the best possible value from Advent Top-Up please check your personal charging structure with your mobile network. Your network will be able to tell you which of the above access codes will be the cheapest for you to use.

You needn't worry too much. The most that any call is likely to cost will be equivalent to your standard calls to a landline. So at worst - you can call the USA from your mobile for the cost of a standard call plus just 1.7p

Can I save dialing time when making international calls?
The Advent Top-Up service is very quick and hassle free. There is even a simple trick that you can use to make the dialing process completely seamless. There is no need for you to dial both the access code and the full international number every time you use the service.

Here's How You Do It:
Simply add a pause between the access number and the international number you wish to dial:

For example: You want to call Mum in Australia. You create a new entry called 'Mum' in your mobile's phone-book memory and when entering the number:

1. Enter the Advent Top-Up access number - 0207 124 6666 or 0800 594 6666 or 0845 451 6666

2. Enter a 'pause'. This can be done easily depending on the brand of your mobile:

Nokia Phones: A 'p' will appear after * has been pressed 3 times. Siemens/Panasonic Phones: A '+' will appear after 0 has been pressed and held. Motorola / Sony Ericsson Phones: A 'p' will appear after * has been pressed and held.

3. Now enter your international destination number in full including 00 and save.

That's it - next time you want to call up your Mum using Just Dial's Advent Top-Up service simply find 'Mum' in your memory and dial!

For definitive instructions please review your mobile phone instruction manual or contact your phone manufacturer.

Can I top up my balance?
Yes. Repeat the original top-up process - that never changes. If you have - for example - 40p remaining credit and you top-up with another £3 you now have £3.40's worth of credit to make calls. Simple!

How many calls can I make?
As many as you want - you can use the Advent Top-Up service any time of the day or night and can keep making calls up until your credit runs out. Remember you can top up any phone you want at any time.
