Writing and Reading the Phonebook

This OpenAT stuff is great,
I have only been using it for a week and I now have a working prototype!

I am currently looking at how to write and read from the phonebook
I was wondering what is the best way to do this?

Using AT commands, or maybe the sims service?

Thank you for all your help

Cheers

If the SIM Service does what you require, use it - otherwise, you will just be duplicating stuff that’s already done!

If it doesn’t do what you require then, of course, you will have to do it yourself with AT commands.
