There's a special way to make international calls on Mobile World. All you need to do is put the magic 2 in front of the number you're calling, then enter the international code (00) and telephone number as usual. It's as simple as:

• Dial 2 (Accesses International service)
• Dial 00 (Exit code for UK telephone system
• Dial the Country Code (e.g. 34 for Spain, 1 for USA)
• Dial the phone number, including the area code if required
• Press the green handset key on the mobile to connect the call

If you forget the magic the magic 2 - you'll hear a message saying that your call has been barred, but you won't be charged. You'll be cut off if you run out of credit during an international call, so check your balance before you make any lengthy calls!

UK Calling:
You can make calls as soon as you're connected and have added some credit to your account. With low, low costs for all calls from your mobile, this is where the savings start! Don't worry, you won’t be cut off if you run out of credit during a UK call. This means your mobile account may become slightly 'overdrawn' on occasions, so we'll deduct any extra call charges from your next top-up. When your account reaches zero, you won't be able to make any more calls until you top-up again.

Text Messaging:
A standard text message can include up to 160 characters. Some mobiles let you send messages of more than 160 characters by breaking the message into shorter parts that are reassembled when they arrive on the recipient's mobile. Clever, eh? If your mobile lets you do this, you'll be charged for the number of separate messages you send. By the way, receiving a message from another mobile phone is completely free.

When sending international SMS, you do not need to dial the prefix 2. Only dial the international code and the recipient number. Your SIM card stores up to ten messages. When your SIM card is full, you may not be able to receive any new messages until you delete some of the old ones, although some mobile phones are able to store additional messages.

Voicemail:
Mobile World has a voicemail service that records a message when you don't answer your mobile phone. It'll then let you know that someone's called and will save the message for when it's convenient. Calling voicemail costs less than making a standard UK call. Of course, you're not charged when someone leaves you a message; you only pay when you call the voicemail service yourself.
