Before you start
- An unlocked handset, or an eSIM-capable one
- A US address for postpaid, but not for prepaid
- A payment method — prepaid accepts foreign cards, postpaid usually does not
Step-by-step
- 1
Activate an eSIM before flying, or buy prepaid on arrival
A US eSIM activates before you land so you have a working number immediately for rides, deliveries and bank verification codes. No identity registration is required at any point.

Check your handset is unlocked and band-compatible
Phones bought on contract abroad are frequently locked, and US band combinations trip up some regional models. With 3G shut down there is no fallback network to land on.

Start prepaid rather than fighting a credit check
Postpaid runs a credit check. With no US file you will be declined or asked for a deposit. Prepaid has no check and is usually cheaper for the same data allowance.

Leave severe weather alerts switched on
The Piedmont gets severe thunderstorms with damaging wind and occasional tornadoes, and the remnants of Atlantic hurricanes reach here as heavy rain and flash flooding every few years. Warnings arrive through the federal wireless alert system; Mecklenburg County also runs its own notification service. Both are worth having.

Shop home internet by address — competition here is real
Much of Charlotte has more than one genuine fibre option alongside cable, and promotional pricing responds to that. Check the address on the FCC's broadband map and use a second quote against the first before signing a 12-month term. Availability changes street by street in the older neighbourhoods.

Port rather than cancel if you switch later
Number portability is a legal right and works between carriers and MVNOs. Request the port from the new carrier — never cancel the old service first, or you lose the number.

Documents you’ll need
- Passport for postpaid; nothing at all for prepaid
- US address for postpaid
- A payment card — prepaid usually accepts foreign cards, postpaid rarely does
Things most newcomers don’t know
The credit check is the barrier, not the documentation.
Carriers check credit before offering postpaid, and a newcomer with no file gets declined or charged a deposit. Prepaid sidesteps it entirely and usually costs less for the same data.

The US has no SIM registration at all.
Most countries in this app require passport registration to activate a SIM. The US requires nothing whatsoever for prepaid — you can buy one in a supermarket and be online in minutes.

Broadband competition here is genuine, so negotiate.
Much of the US has one practical home internet provider per address. A lot of Charlotte has two or three, and the first price quoted is rarely the best available. Check the FCC's broadband map for the specific address and use the second quote against the first.

Hurricanes reach here, just not as hurricanes.
Charlotte is around 300 km inland, so it does not get storm surge or the worst wind — but the remnants of Atlantic systems arrive as sustained heavy rain and flash flooding on the creeks, and Hurricane Hugo in 1989 is still the local benchmark for wind damage this far inland. Keep the alerts on and know whether your street is near a creek.

Common mistakes to avoid
- Applying for postpaid with no credit file and facing a large deposit.
- Bringing a carrier-locked handset from abroad and discovering it on arrival.
- Silencing weather alerts after one loud test, and missing a tornado or flash flood warning.
- Signing the first home internet quote without checking who else serves the address.
- Cancelling the old carrier before requesting the port, and losing the number.
