Can you link Mighty Text (etc) to a dumbphone?

[AC Question]

A friend (with arthritis in her fingers and thumbs) has a dumbphone she will not be parted with, but I have managed to facilitate her to get a tablet - Nexus 7 (2013) - and broadband.
If her phone was a smartphone I would link her in to Mighty Text for ease of texting whist not straining those already sore digits. What app can she put on her tablet so she can text with a stylus (which she likes) using her EE phone package?
Thanks for any ideas. Lenilen.

Welcome to the forums. Is it just you two texting between each other? You could try Hangouts, as an IM app. Most texting apps will probably require a phone number check, which the Nexus tablet might not have.
