When you have you local SIM card with you (Beeline operator is the best option), it takes less than a minute to activate, which can be checked by the name of the service provider which appears on your cell phone screen. The number will be for eg. +998 (country code) 90 (service provider code) 1234567 (actual seven digit cell phone number). You may make calls to anyone locally by only dialing the last seven digits. You may send a text message to anyone locally by using the entire number, or internationally by using the country code (for eg. India +91) followed by their ten digit mobile number. Incoming is not charged and hence, you can receive calls or text messages, from your friends, family and relatives if they dial the entire number eg. +998 90 1234567.
