GSM options for Connected Bracelet ?

[LIFER.1]

Hello, as part of a connected bracelet project intended for the medical surveillance of the wearer and alerted in case of emergency, we would like to know your on-board solutions allowing us a gsm connection in order to send data relating to the health of the wearer and transmission channel. we want an MCU solution but also rf via esim.

Other interfaces such as the use of an accelerometer, gps are envisaged.

On the site, I identified references esim ST33K, ST4SIM-200M ???

Which Micro would be suitable for my application?

What type of starter kit can I source from to test the solution?

Thank you
