How to send an e-mail with SMS module?

[Der_Rote]

Hello,

 

I work with a STM32L031K6TxLQFP32. I can already send a SMS by connecting a SIM card.  Can someone tell if I can control a SIM card, so I can send and received an Email or, if it doesen't work, because of what value it would fail?

Thanks in advance.

Hello @Der_Rote and welcome to the ST Community :smiling_face_with_smiling_eyes:.

That depends on the sim module that you arr using. For example, if you are looking to send email using the module sim900, it will be possible using the AT Commands.

Best Regards.

There's often an SMS method to an email address. Depends also on carrier / plan. Might also find SMS redirectors that can do it.

Not just a SIM card - you'd also need a GSM (cellular) radio module!

The SIM card is just your authentication to use the network.

To send an email, you'd need to implement an email client (eg, SMTP), which would also require a TCP/IP stack.

As @STTwo-32 suggested, many cellular modules have such things built in - access via AT Commands.

Or, as @Tesla DeLorean suggested, you may be able to find an SMS-to-email gateway service ...

BTW: note that GSM (2G & 3G) services are being phased-out (already gone in some places) - so probably not a great idea to be starting a project now based on a 2G module like SIM900...

What worked for me was registering the SIM with a sip provider that offers email-to-SMS or SMS-to-email services. Once your module can send AT commands correctly, the sip provider handles the rest by routing the message as an email through their gateway. Just make sure the module’s firmware supports the extended AT command set for SMS functions.

GRPS is not supported by modern cellular networks (4G, 5G). It is still supported by some 3G networks. 

To send email using SMTP or IMAP protocols, your SIM must have a data plan active. Otherwise you can only send SMS (so, SMS to email gateway - as suggested by others).
