Staying Connected

Phone service abroad

This isn't about avoiding roaming charges on a two-week trip — it's about staying reachable for the things that don't stop needing you: bank logins, Social Security, two-factor authentication codes. The carriers built for travelers (Google Fi, T-Mobile's international plans) aren't built for people who've actually moved, and most people don't find that out until they're locked out of their own bank account from another country.

Sort your phone out before you leave, not after you land. The whole strategy below depends on your phone being unlocked and eSIM-capable — that's a five-minute check or a purchase decision made easily from the US. Trying to sort it out once you're already abroad is a much harder problem.

Before you leave

Confirm your phone is unlocked and dual-eSIM capable

If your phone was ever on a carrier contract — even one you've since paid off — it may still carry restrictions that block a second provider's eSIM. Any recent iPhone or Google Pixel handles two active eSIMs cleanly, but not every budget Android model does.

Before you leave

Activate a US number built to survive going abroad

Google Fi and T-Mobile both restrict service after extended time outside the US — the exact opposite of what a permanent move needs. US Mobile or Tello are built on major networks but registered as genuine carrier numbers, not VoIP, so they pass the bank and government 2FA checks that services like Google Voice sometimes fail. This becomes your permanent line for anything that texts or calls you a verification code.

Once you've landed and settled

Add a local SIM or eSIM for daily use

Once you have an address, a bank account, and a working understanding of the local landscape, add a local carrier's SIM or eSIM alongside your US line. This becomes your daily-use number and data plan — cheaper and better-suited to local coverage than any US carrier's international add-on. Your US line stays active in the background the whole time, still receiving 2FA codes without interruption.

Ongoing

Keep your US line's billing current

These low-cost carriers exist specifically to stay active with minimal use — but they still need a valid payment method and occasional login to avoid lapsing. Treat it the same as any other account you can't afford to lose access to.

Phone service checklist

Confirm your phone is unlocked — request this from your carrier for free if it isn't already
Verify your specific phone model supports dual eSIM before buying or relying on it
Activate a US Mobile or Tello line before you leave, not after
Log into every bank, brokerage, and government portal (Social Security, IRS) and confirm 2FA delivers to your new number
Save your new number in writing somewhere other than your phone, in case you need to give it to an institution while abroad
Once settled, research local SIM/eSIM options for your specific destination
Set a reminder to check your US line's billing periodically so it never lapses
