How do you make calls either to the UK or to number in same country from your mobile when abroad?

Answer 1

The best and most reliable way, if your mobile phone supports it, is to enter all numbers in international format. The GSM mobile network (and some, but not all, non-GSM mobile networks)will automatically substitute any necessary prefixes.

The country code for the UK is +44, and you must drop the leading 0 from the UK domestic number. For example, Liverpool's 0151 becomes +44 151.

In most other countries, you must drop the leading 0 from the domestic number and replace it with the country code, beginning with the plus symbol. Note that country codes never begin with zero. Note also that there are exceptions to this rule, most prominently Italy, country code +39. For example, Rome's area code 06 becomes +39 06 in international format.

The procedure for entering the plus symbol varies, depending on the specific make and model of cellphone you have. On some phones, you press 0 twice; on others, you hold the 0 key until the 0 turns into a +. Other phones may have other procedures, but your user manual should have the necessary details.

(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
