I've tried putting my cellphone number to get orange clearance a month ago, but I never received a confirmation call or text. Since my phone service provider is from Mexico, i thought this was an issue with the country code or something along those lines. Back then, I used "011 52" as the country code, since it's the code to make calls to Mexico from USA. I tried recently to use the code to make calls from anywhere to Mexico (+52), but the game doesn't let me use the + symbol. Is there an specific code i should use?
