Budget?
Who do you want to chat with, and what do they have? (Go with that.)
Cellphones have their obvious limitations of requiring infrastructure to do anything. Boosters help.
Satphones, expensive... both hardware and minutes. They're not as fast/easy as a cellphone, so don't think that you're just going to dial a number, press send, and talk. Latency and dropped calls are still a major problem with them. And did I mention they're really expensive?
That said, they're a great emergency tool to have if you're way back innawoods and out of any service area.
PLB/Communicators are also good emergency tools, but for the most part they're one-way "I need help here ASAP" (Two-way devices do exist, google "InReach" for more info. Probably beyond the scope of this thread.)
CB's are still popular in some groups. Antennas are huge, co-channel users are ... interesting, at times. Power requirements and antenna size make portables miserable to use; mobile's really the only way to go with that. Which is fine, till you want to get out of the truck.
FRS/GMRS is my typical recommendation. Radios are cheap, offer a shitload of options/accessories. Good range. In the snowmobile/moto world, damn near everyone has one. Radios are small, get great battery life. Downside, due to regulations they're only available in a portable/handheld unit (no mobiles (legally)).
GMRS is a $70/10yr license, covers immediate family members, and grants you legal permission to use the high-power (2W+) modes on portables, up to 50W for a single-site repeater.
MURS is a VHF license-free business band that some people use. Great if you're in one group and don't need comm with anyone else, but be aware in an emergency situation, they're really limited due to the lack of interoperability. Recommend keeping at least one FRS/GMRS radio in the group if you go this route. I don't advise using this.
Amateur gets you a ton of power, a ton of options, a ton of equipment choices. While this thread will probably drift to an amateur discussion, i'm going to keep it short for now. Downside is the license requirements (Easy, but still a time/study commitment) and <$20 exam fees.
A baofeng (shitty chinese radio) will get you the basic equipment you need for under $50. Personally, I'd pony up the $200-ish on a decent Kenwood/Icom/Yaesu portable if you're somewhat serious about it... get something that's going to last.
Commercial/Part-90 stuff ... is great, you get your own private frequency (or frequencies), but $$$$$$$ and administrative duties.
tl;dr: For a radio, I'd go FRS/GMRS. If you're looking for something "more better", step into the world of amateur radio.
