Gmail on your phone using SMS
This feature is currently only available to those in Ghana, Kenya, or Nigeria who have an email address ending in "gmail.com."
Gmail lets you use email on any cell phone, even basic phones that only support voice and SMS. You'll receive, reply, and send emails as SMS messages, regardless of whether you have a data connection like wifi or 3G.

Getting started

Here's how to start using Gmail SMS on your phone:

Go to Gmail.
Click your profile photo at the top of any Gmail page and click Account.
Click Open SMS settings in the "Phone and SMS" section.
Add or edit your phone number to receive Gmail to that number.
Verify your phone number by entering the verification code that we sent as SMS to your phone.
Check the box for email forwarding to your phone.
Once you start Gmail SMS, you can also reply to emails and compose new emails as SMS.

Here are a few details about this feature:

Receiving email: Gmail SMS is based on a credit system. Receiving email is free, starting with a 30 email credit. Every time you reply to an email by SMS, send a command (e.g. MORE, HELP) or compose a new email, you get 7 more free emails. Gmail SMS will notify you if your credit is close to 0.

Mobile operator charges: Receiving SMS is free of charge, but your standard rate charge applies to each SMS sent from your phone, be it a reply or any command.

Mobile operators supported:

Ghana - Airtel, MTN, Tigo, and Vodafone
Kenya - Airtel, Orange, Safaricom, and Yu
Nigeria - Airtel, Etisalat, Glo, MTN, Starcomms, and Visafone
Note that if you switch a mobile operator without changing your mobile number, Gmail auto-forwarding will discontinue.
