The Palm Treo came out in 2002. No: every Treo relied on 2G or 3G networks, all shut down in the US.
The quick answer
- Calls: no
- Software: Palm OS or Windows Mobile
- Still works offline for some features
- Worth keeping as a collectible
Why it can't connect
Treos used GSM or CDMA networks that no longer exist. None support 4G.
What still works
Palm OS models still run their built-in apps: calendar, contacts, memos and games. Syncing needs an old PC with Palm Desktop.
What it's worth
Popular models include the Treo 600, 650 and 755p. Working units with a stylus and charger sell best.
If you're replacing it
A new moto g 2026 or Galaxy A17 costs little, gets years of updates, and several carriers give them away when you switch. Pair it with a low-cost plan such as Mint Mobile ($15 a month for 6GB on a 12-month term) or Visible ($25 for unlimited, taxes included).
Current offers from Metro, T-Mobile, Verizon, AT&T and Xfinity.
