Generally we exchange mail via Gmail. In addition to mail exchange, Gmail can be accessed through a lot of benefits. One such advantage is to save the phone number through Gmail.

All mobile numbers will be lost if the mobile phone is lost or the SIM card is lost. Because of this, you can save numbers from the smartphone to the mobile number in Gmail.
For this, go to your smart phone contact list and click on the option. After that click Export / Import from there. There you will find an option for your Gmail address and click on it. Now copy your numbers and save to Gmail. Save the number from Gmail to now.
