Data, SMS and 3G calls all work flawlessly.
MMS not tested with latest software but probably the same as ID mobile as they appear to use the same underlying MMSC.
In practice, according to Cellmapper.net, almost all _Three_ cell sites seem to operate on bands 3, 1 and 20, with 3 the most common, followed by 1, and 20 the least common. Where other bands are used, they seem to be in addition to these main bands, so modem compatibility is a non-issue.
\*I had VoLTE enabled all the time and found it worked fine for me, but see note about VoLTE on ID Mobile, which might also apply to Three as it’s the same physical network (not tested).

MMS is a work in progress. After inputting the carrier’s settings, I can currently receive MMS messages fairly reliably but I can not reliably send MMS messages. I need to investigate logs and report a bug when I find the time to do so.
For some reason, the operator’s name appears as i" instead of iD on the Librem 5, but this does not seem to affect operation. Again, I need to report that as a bug at some point.
\*I have VoLTE enabled all the time, and it works fine for me almost all the time. This has remained consistently the case, except that, one year ago, I discovered at least one specific geographic location where the phone would not ring for incoming calls when using VoLTE, making it seem like I was ignoring calls and breaking outgoing calls. I had to switch to 3G in that location. \[forum post\] 1 It’s possible the experience may have improved since then, as I haven’t tried making or taking a call in that location recently. VoLTE still works fine in the places where I normally use it.

\* Purism developer Sebastian Krsyszkowiak [says](https://forums.puri.sm/t/questions-about-dogwood-and-phone-calls/10156/23) this is caused because the Librem 5 doesn't support VoLTE:
> There’s no VoLTE, so it drops to 3G when in call. This would mean that there’s no 3G reception where you live, so it makes it drop all the way to 2G (but data should still work, although much slower - unless there’s something wrong carrier side of course).
The BM818 has VoLTE support but it is not enabled by default. This is still a work in progress.
