A command I've found which changes the authentication method from the command line is: /usr/share/ofono/scripts/set-context-property 1 AuthenticationMethod pap The number may vary depending on which order the APNs are displayed in /usr/share/ofono/scripts/list-contexts. I found this on https://docs.droidian.org/info/apn/

@bhdouglass Thank you very much. I've uploaded the corrected version. The store page doesn't seem to display the version number on the website - this doesn't appear to affect the Open Store app.

@ultrasonicnoise Hmm ... so if that APN is no longer in the file, then maybe it is not matching the "3" in the name field and so it defaults to what the provider or sim card sets? (I am assuming that is what it uses to match ... ) Sorry, not sure what to suggest from here ... ?? <provider primary="true"> <name>3</name> <gsm> <network-id mcc="234" mnc="20"/> <apn value="three.co.uk"> <usage type="internet"/> <name>3 Internet</name> </apn> <apn value="3internet"> <plan type="postpaid"/> <usage type="internet"/> <name>Internet</name> </apn> <apn value="three.co.uk"> <usage type="mms"/> <name>3 MMS</name> <mmsc>http://mms.um.three.co.uk:10021/mmsc</mmsc> <mmsproxy>217.171.129.2:8799</mmsproxy> <!-- mms.three.co.uk --> </apn> </gsm> </provider>

@keneda I thought so. Thank you very much for confirming.

@barryt I have been running 20.04 Development channel for a few days now and everything is working perfectly; SMS messages come through in just a few seconds. I shall post on the Github link. Thanks for the help.

@ultrasonicnoise https://www.xda-developers.com/15-second-adb-installer-gives-you-lightning-fast-adb-fastboot-and-driver-installation/ might just be windows for linux just use terminal commands (seach on net).

@kugiigi That's it posted now. https://gitlab.com/ubports/development/core/messaging-app/-/issues/316

@keneda I think I have the hang of it. Thank you very much.

@mrt10001 Thank you so much. Using Chromium to flash a phone was an odd experience but I'm pleased to say it works a treat now.
