Relocating for work, studying abroad, or a working-holiday year. As you get ready to leave home for a year or more, have you found yourself pausing at one question: “What should I actually do about staying connected?”
Will you have reliable service once you arrive? Can you keep using your bank and subscriptions back home? Will it be easy to stay in touch with family? It’s rarely just one worry.
This guide is a map to help you move forward one confident step at a time, from before you leave until you come home. We’ll break down the jargon as we go. There’s no rush—start wherever you need to.
For a first long stay abroad, the connectivity setup can feel like “I don’t even know where to begin.” But if you split the work into stages and check them off one by one, you can get everything in order without any special expertise.
How to use this guide — which stage are you in right now?
This guide follows the flow of life abroad and is split into four stages. Just start with the part that fits you today.
- Still at home, getting ready → jump to “Before you go: getting your connectivity sorted”
- Just arrived and want to get activated → jump to “On arrival: activating your eSIM and handling SMS verification”
- Settled in and thinking about cost or hiccups → jump to “While you’re there: saving on data and preparing for ‘no signal’ moments”
- Getting ready to head home → jump to “Coming home: wrapping up contracts and restarting your line back home”
Each stage also links out to a more detailed article. If a topic catches your eye, follow it to the deep-dive.
Where to read changes with your stage: before departure, just after activation, mid-stay, and before heading home
Life abroad moves through stages—“prepare → activate → settle in → head home”—and what matters to you shifts at each one. Notice which stage you’re in, start from the list above, and you’ll get straight to the information you need. Bookmark this page so you can come back as you move from one stage to the next.
Why so many long-stay travelers choose an eSIM
There are several ways to stay connected during a long stay, but one that’s increasingly popular is the eSIM. The appeal: you can set it up online before you leave and start using it soon after you land. That means less hunting for a SIM card at the airport and less struggling with the language at a counter.
What is an eSIM? The difference from a physical SIM, made simple
An eSIM is a SIM that’s built right into your phone. Instead of swapping a tiny plastic card (a physical SIM), you download and configure the details.
| Physical SIM | eSIM | |
|---|---|---|
| How you get it | Mailed to you or picked up in store | Delivered online |
| Swapping cards | Required | Not needed (switch in settings) |
| Risk of losing it | Yes | Low |
Note: whether a device supports eSIM, and the conditions for using one, vary by model. To check whether your device works, see our device compatibility guide or the comparison page.
Three things worth prioritizing for stays of a year or more
- Ease of keeping it going: unlike a short trip, how easy it is to renew or top up data really starts to matter.
- Keeping your home-country services working: how to maintain SMS verification and contact back home (see Keeping your services back home for details).
- Support when things go wrong: whether there’s help you can lean on when you can’t get a signal.
On a short trip you can shrug off a bit of inconvenience as “just a few days.” Over a year or more, small frictions add up. That’s exactly why it’s worth looking beyond price alone and asking, “Can I keep this up comfortably?”

Before you go: getting your connectivity sorted
The biggest tip for prep is simple: don’t leave it to the last minute. Trying to do everything right before departure makes it easy to miss something. Let’s work through it in order.
Check whether your device supports eSIM
Start by confirming that your current phone supports eSIM. If it doesn’t, you’ll want to consider another option or device. The steps differ by model (iPhone, Android, and so on), so follow our device compatibility guide. It’s also worth checking whether your phone is carrier-locked.
Decide what to do about your home-country phone number and SMS verification
This is the part many people overlook—and a big one that tends to cause trouble later. If you’ll still need SMS verification codes from your bank, brokerage, or other services back home while you’re abroad, decide before you leave how you’ll keep that number active. There are several ways to hold onto a number, each with its own pros and cons (see → Keeping your services back home / How to keep your home-country phone number).
One thing worth knowing: a travel eSIM is typically data-only—it doesn’t come with its own phone number, SMS, or voice calling. That’s why keeping your existing home-country number active matters so much for verification codes.
Pre-departure checklist
- Confirmed your device supports eSIM and checked for a carrier lock
- Decided what to do with your home-country number (keep it / suspend it temporarily, etc.)
- Listed the services back home that require SMS verification
- Got a rough idea of the plan you’ll use at your destination
- Saved or printed the activation steps (so you can read them offline)
The best plan depends on where you’re going and how long you’ll stay. Supported countries, data amounts, durations, and the like vary by plan and device, so check the comparison page for the latest details.

On arrival: activating your eSIM and handling SMS verification
Once you land, it’s time to activate. This is where a lot of people get stuck, but if you follow the steps, you’ll be fine. Take it calmly.
The basic activation steps
Activating an eSIM roughly follows this flow: “load the settings → enable the line → confirm you’re online.” The exact screens and steps depend on your device and the service (scanning a QR code, manual setup, and so on). Check the activation guide for your specific plan.
We recommend activating where you have Wi-Fi (an airport or hotel, for example), since downloading the setup details usually requires a connection.
Will my home-country SMS verification still arrive?
“Once I start using a local eSIM, will my SMS verification codes from back home stop coming through?” This is a very common worry. The answer depends on how you’ve kept your home-country number. Generally, whether you can receive codes comes down to keeping that number active. Because a travel eSIM is data-only and has no number of its own, the codes still go to your original line. We cover the causes and fixes when codes don’t arrive in a dedicated article.

While you’re there: saving on data and preparing for “no signal” moments
The longer your stay, the more it pays to have a healthy relationship with your data costs. Knowing “what to do when you can’t connect” also means you won’t panic when it happens.
Tips for managing data without the stress
Don’t deprive yourself—just trim the waste. That’s the secret to keeping it up. Lean on Wi-Fi at home and in cafés, and save big downloads like video for when you’re on a good connection. Even that alone makes a noticeable difference. Setting app auto-updates and backups to run on Wi-Fi only helps too. Data amounts and top-up methods differ by plan, so check our data-saving tips and the comparison page.
A calm troubleshooting routine when you can’t connect
When you can’t get online, a few basic checks usually sort it out.
- Toggle airplane mode off and on
- Review your line and APN settings (the values vary by plan and device)
- Check that you’re in coverage and the line is enabled
- If that doesn’t fix it, contact support
The exact APN values depend on your plan and device. For steps tailored to your setup, see our APN and line-settings guide for when you can’t connect. Keep in mind that real-world signal and speed can vary with the local network, your device, and your specific area.

Keeping your services back home (banking, brokerage, subscriptions, and staying in touch) while abroad
One thing that worries people more than expected when living abroad is “Can I keep using my services back home?” Logging into your bank or brokerage, keeping subscriptions running, and staying in touch with family—all of it ties directly to daily life.
Common stumbling blocks for keeping home-country services
- Not receiving SMS verification: depends on how you handle your home-country number (→ Before you go / On arrival)
- Region restrictions on home-only services: availability and conditions vary by service. Check each provider’s guidance for whether it works abroad
- How you stay in touch with family: pick by purpose—voice, video, or simply checking in. A data eSIM pairs well with messaging and calling apps such as WhatsApp; choose whatever your family already uses
For all of these, deciding before you leave shrinks most of the worry. In particular, the verification methods used to log into banking and brokerage accounts can be hard to change once you’re abroad, so it’s best to sort them out before departure.

Coming home: wrapping up contracts and restarting your line back home
Once the return date comes into view, don’t forget to tidy up your contracts. Work through what to do with the travel eSIM you no longer need, and how to restart your line and services back home, in order.
What to do around your return
- Check whether you need to cancel or pause your travel eSIM/plan (conditions vary by plan)
- Restart or re-sign your home-country mobile line
- Point SMS verification back to your home-country number
- Resume any services you paused while abroad
Cancellation and pause conditions and timing differ by plan, so it’s reassuring to check your contract terms ahead of time. If you’re unsure of the order of steps, see our guide to getting set up again after you return.

How to choose the plan that fits you (your next step)
By now you might be thinking, “So how do I choose for my situation?” The three things that matter most are your destination, your length of stay, and how you use data. Choosing comfortably around those is the key to keeping it up over the long haul.
Specific plan details (supported countries, data amounts, durations, compatible devices, and so on) vary by plan. We keep the latest information on the comparison page, so take a look there too.
