In this guide you will learn how to quickly 

set and run ESIM251 device manually 

 

(using SMS messages for programming). Here are the most important steps:

*1 - PIN code can be disabled by putting SIM card into mobile phone and following proper menu. *2 - User must type mobile number in the international format (it consist of only those digits that 
overseas callers must type: 44<area code><local number>) without symbol ‘+’. E.g. the mobile number of user is +44 (0) 113 xxx xxxx,  so the correct format to type is 44113xxxxxxx and the wrong 
ones – 440113xxxxxxx or  0113xxxxxxx. *3 - device will use default settings set by manufacturer. The settings can be changed by user at any time.
