@grisen no problem.
I don't know how to code, so I just donate.
This answer is not just for you but for all the people reading the forum. There are other ways to help the project too, like translating, beta-testing, confirming bugs in the bug tracker, writing documentation, helping with UT installation, solving newbies doubts, etc
Who can help me with SMS/MMS? I'll be happy to supply logs etc..
A good starting point is searching what is reported already, and then add your experience to an open bug report, or create a new bug report if it doesn't exist yet.
For example, you could start here https://github.com/ubports/ubuntu-touch/issues?utf8=✓&q=is%3Aissue+is%3Aopen+mms
I'm curious about helping but like many, have no technical education. I have a Nexus 4 and a 1+1 for about 8 weeks now. So I suppose I can, Test Bugs? on either. Feeling a wee helpless, I made a donation tonight as I really hate Android and Blackberry OS10 is being given Benign Neglect.
