When it comes to making international calls, Lycamobile works in the same way as other mobiles or landlines.
Simply dial 00 followed by the country code you are calling (e.g. 40 for Romania), then the area code without the first 0 (except Italian landlines where the first 0 is kept) and then the phone number and press the call button. Instead of 00 you can also use a “+” (e.g. +40).
For example, if you were calling Romania from the UK, you would dial 0040377 881276 (example is Lycamobile Customer Services).
Please note that most premium voice and text services in other countries cannot be reached from a mobile phone service when calling from outside that country.
