Numbers format

All numbers should follow the international format; for that, you need the country prefix. It's really important for all numbers to follow this format, without it, you might end up sending or calling the wrong country!

Add the country prefix, and take off the + and the first 0 from the number:

• Dutch number, country prefix(+31): 0612345678, should be entered as 31612345678
• UK number, country prefix (+44) s: 0712345678, should be entered as 44712345678

Make sure the mobile phone numbers you enter are correct and valid so you don't waste balance on messages sent to non-existent phone numbers.
