My friend called me from UAE, the number is 07 15830 ... how can I call him back?

Your number is not from the United Arab Emirates. If you call from the United Arab Emirates, if the number is not garbled, it will display +97 15 ... if you call from a mobile phone, +97 12 ... if you call from a landline, Abu Dhabi will display +97 14 ... and so on. . If this is the case, you can dial it back directly.

However, when foreign calls come in, garbled codes may appear in the transmission. The most common display is 000 19 ... what, if you use this display mode, you can't dial back. Another possibility is that it displays a domestic number, or a domestic mobile phone number, or a domestic landline number, which is also impossible to call back.

If you want to call back, you can only ask him his mobile phone number, starting with +97 1
