As far as I am concerned, lucky mobile caters to clients with french requests. For example: an agreement from the company that is written in the French language, you could have that. So, i do think that it is possible to put a french mobile number. Hope it helps! I guess you could always refer to their assistive chat feature on their website for faster accommodation.
Hi Dele. What do you mean by French mobile number? If you want to change your number, try contacting Lucky Mobile.
