Sure. Note, though, that what you're doing there is effectively making said town part of your community (in the context of who "has" what technology, in any case).
Consider these scenarios:
You show up to some remote island, build a bunch of cell towers, hand out mobile phones, and leave, never to be seen again.
vs.
You show up to the neighboring town, build a bunch of cell towers, which you connect to your own cell network, hand out mobile phones, and continue to administer and maintain said towers, and provide support for said phones.
In the latter case, yeah, this community now has cell phone technology. But only because they're a part of you now. If you cut them off from yourself — by ceasing to provide maintenance and support for the technology you just gave them — they no longer have any technology, just a bunch of artifacts which work (for a while, anyway), but are as magic.
Semantics aside, I agree with the particulars of what providing cell phones (in a functional sense) to a town that can't manufacture them itself comprises.
And I'm willing to use that definition of "part of my community" in this conversation if you like, though of course there are many implications of that phrase which don't apply to the scenario in question, so we should be careful about connotations.
I'm not sure why it matters, though. Does something additional follow from that town now being part of my community (in this sense)? If so, perhaps it would be useful to state that consequence explicitly, because I'm not seeing it.
Rationality quotes time!
