Yup, was very easy. No issues at all. Make sure to save your key in a safe place, print it and also save it to your cloud, your phone, etc. I like to keep copies in multiple places.
Depends on where you live, but DMR was the most useful to me, NXDN doesn't see much use but I do have it, and Provoice is obsolete but some places still have it in use. The subway system near me still uses it but that's literally it, so I didn't bother getting that upgrade.To my knowledge a lot of trains are switching to using NXDN anyways
Have fun
