Introduction
A phone is the first thing you need to arrange after arriving — work, bank, doctor. Without an SSN, you cannot sign a long-term contract (postpaid), but prepaid works with a passport. Prepaid plans are cheap and without obligations.
Prepaid vs postpaid
- Prepaid: you pay in advance; no contract, no credit check
- Postpaid: contract for 12-24 months, requires SSN + credit; more expensive
- Start with prepaid; after 6-12 months (once you build credit), you can switch to postpaid
Three networks (carriers)
- Verizon — best coverage, most expensive
- T-Mobile — great 5G in cities
- AT&T — wide coverage
Other brands (MVNO) use one of the three networks.

Phone — buy in the USA or bring from home
- A Polish phone — works in the USA if "unlocked" and supports USA bands
- iPhone from 2018 — all bands OK
- Samsung Galaxy global versions OK
- Xiaomi/Huawei — check bands (B66, B12, B71)
- New in the USA: iPhone SE from 430 USD; Galaxy A35 from 400
Wi-Fi calling — crucial
- All US carriers support it — call over WiFi at home
- A Polish phone with a Polish SIM + Wi-Fi calling = free calls to PL (if the PL carrier supports it)
- Better: WhatsApp, Messenger, Signal — free globally
Common mistakes
- 50-80 USD/month postpaid when Mint offers the same for 15
- No Wi-Fi calling — quick consumption of minutes/data
- Roaming in Poland — expensive; turn off mobile data
- Polish SIM in the USA — very expensive roaming
- Not using eSIM — iPhone supports two numbers simultaneously
