Regularly unable to send and receive MMS. Although Internet use (non WiFi) is fine when out and about.
Reset network settings makes no difference, still doesn't function.
Manually creating APN allows briefly sending/receiving of MMS, but then manual settings appear to magically disappear, only for everything to default APNs, and nothing to work. Default APN settings must be coming from SIM card, and visually cannot see any incorrect settings, but Nokia 6 does not allow modification of the settings - they appear 'greyed out'.
