An overseas job posting, studying abroad, a working holiday. As you get ready to leave home for a year or more, have you found yourself pausing at one question: “What am I going to do about staying connected?”
- For long stays, an eSIM is convenient—you can set it up online before you leave and start using it as soon as you arrive
- A data-only eSIM has no phone number, voice calls, or SMS, but app-based calls (WhatsApp and similar) work fine
- Whether you keep receiving SMS verification from your home country depends on how you keep your home number—decide your approach before departure
- Always check your device’s eSIM support and SIM-lock status before you leave
- When you head home, cancel the eSIM and switch your SMS verification back to your home-country number
Will it actually connect once you’re there? Can you keep using your bank and subscriptions back home? Can you stay in regular touch with family? The worries rarely come one at a time.
This guide is a map to help you move forward step by step, without second-guessing, from before departure all the way to coming home. We’ll break down any jargon as it comes up. No need to rush—start wherever you need to.
If this is your first long stay abroad, setting up connectivity can feel like you don’t even know where to begin. But if you split the work into stages and check them off one at a time, you can get it all sorted without any special expertise.
How to use this guide: which stage are you at right now?
This guide follows the natural flow of life abroad, split into four stages. It’s perfectly fine to read only the part you need right now.
- Still preparing to leave → go to “[Before you go] Getting your connectivity ready”
- Just arrived and want to get connected → go to “[On arrival] Activating your eSIM and SMS verification”
- Already settled in, thinking about saving money or fixing issues → go to “[During your stay] Cutting costs and preparing for “no signal” moments”
- Getting ready to head home → go to “[Coming home] Wrapping up plans and restarting your home line”
Each stage also links out to a more detailed article. If a topic catches your eye, dive into the deep-dive piece.
Where to read changes by stage: before departure, just after activation, mid-stay, before heading home
Life abroad moves through stages—preparation → activation → settling in → going home—and what matters to you shifts at each one. Keep track of which stage you’re in, start from the relevant link above, and you’ll get straight to the information you need. Bookmark this page so you can come back as each stage arrives.
Why an “eSIM” is a popular choice for long stays
There are several ways to stay connected during a long stay, but one that’s been chosen more and more lately is the eSIM. The reason: you can set it up online before you leave and start using it right after you land. It cuts out hunting for a SIM card at the airport or struggling with the language at a shop counter.
What is an eSIM? The difference from a physical SIM, made simple
An eSIM is a SIM that’s built into your phone from the start. Instead of swapping a tiny card (a physical SIM), you download the information and set it up.
| Physical SIM | eSIM | |
|---|---|---|
| How you receive it | Mailed card or picked up in store | Received 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 it, vary by model. To check whether your device works, see the compatible-device check guide or the comparison page.
Three things worth prioritizing for a stay of a year or more
- Ease of keeping it going: unlike a short trip, how easy it is to renew or add data really starts to matter.
- Keeping home-country services running: how to maintain SMS verification and contact back home (→ more in Keeping your home-country services).
- Support when things go wrong: whether there’s help you can lean on when you can’t connect.
On a short trip you can shrug off a bit of inconvenience as “just a few days,” but over a year or more, small hassles add up. That’s exactly why it pays to look beyond price alone and ask, “Can I keep this going comfortably?”

[Before you go] Getting your connectivity ready
When it comes to pre-departure prep, the biggest tip is simply not to rush. Trying to cram it all in right before you leave makes it easy to miss things. Let’s go through it in order.
Check whether your device supports eSIM
First, check whether the phone you currently use supports eSIM. If it doesn’t, you’ll need to consider another option or device. The steps differ by model—iPhone, Android, and so on—so see the compatible-device check guide for the exact procedure. While you’re at it, checking whether the device is SIM-locked will give you extra peace of mind.
Decide what to do about your home-country number and SMS verification
This is something many people overlook, and it’s an important point that tends to cause trouble later. If you want to keep receiving SMS verification from your home-country bank, brokerage, and other services while you’re abroad, you need to decide how to keep your home number active before you leave. There are several ways to keep a number, each with its own pros and cons (more in → Keeping your home-country services / how to keep your home phone number).
Pre-departure checklist
- Checked your device’s eSIM support and SIM-lock status
- Decided how to handle your home-country number (keep it / pause it temporarily, etc.)
- Listed the services that need SMS verification from home
- 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 changes with your destination and length of stay. Supported countries, data amounts, durations, and other details vary by plan and device, so check the comparison page for the latest information.

[On arrival] Activating your eSIM and SMS verification
Once you arrive, it’s finally time to activate. This is where a lot of people stumble, but if you follow the steps, you’ll be fine. Let’s take it calmly.
The basic activation steps
Activating an eSIM roughly follows this flow: “load the settings → enable the line → confirm you have a connection.” The exact screens and steps differ by device and service (scanning a QR code, manual setup, and so on). Check your plan’s activation guide for the specific procedure.
It’s best to activate where you have Wi-Fi (an airport or hotel, for example), since downloading the setup information usually requires a connection.
Can you still receive SMS verification from home?
“Once I start using a local eSIM, will I stop getting SMS verification from home?”—this worry comes up a lot. It depends on how you kept your home number. Generally, whether your home number is still active is the prerequisite for receiving those messages. We cover the causes and fixes for when messages don’t arrive in a dedicated article.

[During your stay] Cutting costs and preparing for “no signal” moments
The longer your stay, the more how you manage your data costs matters. Knowing what to do when you can’t connect also means you won’t panic when it happens.
Tips for managing data without overdoing it
Don’t deprive yourself—just trim the waste. That’s the key to keeping it sustainable. Make good use of Wi-Fi at home or in cafes, and save heavy traffic like video for when you’re on a solid connection. Even that alone makes a noticeable difference. Setting app auto-updates and backups to run only on Wi-Fi helps too. Plan data amounts and top-up methods vary by plan, so check our cost-saving tips and the comparison page. Keep in mind that actual connection quality varies with the local network, your device, and the area you’re in.
A calm checklist for when you can’t connect
When you can’t connect, a few basic checks usually solve it.
- Toggle airplane mode on and off
- Review your line and APN settings (values vary by plan and device)
- Check that you’re in coverage and the line is active
- If that still doesn’t fix it, contact support
The specific APN values differ by the plan and device you use. For how to check on your own setup, see the guide to APN and line settings for when you can’t connect.

Keeping your home-country services (banking, brokerage, subscriptions, contact) while abroad
One thing that worries people abroad more than expected is whether they can keep using their home-country services. Logging into your bank and brokerage, keeping subscriptions running, and staying in touch with family—all of it is tied directly to daily life.
Common stumbling points for keeping home-country services
- Not receiving SMS verification: depends on how you handle your home number (→ Before you go / On arrival)
- Geo-restrictions on home-only services: whether you can use a service, and under what conditions, varies—check each service’s own guidance for availability
- How to stay in touch with family: choose by purpose—voice, video, or simply checking in
In every case, deciding before you leave shrinks a lot of the worry. The verification method you use to log into your bank and brokerage, in particular, can be hard to change once you’re abroad, so it’s best to sort it out before departure.

[Coming home] Wrapping up plans and restarting your home line
As your return comes into view, don’t forget to tidy up your plans. Handle your no-longer-needed overseas eSIM and restart your home line and services, in order.
What to do around the time you head home
- Check whether you need to cancel or suspend your overseas eSIM/plan (conditions vary by plan)
- Restart or re-sign up for your home line
- Switch your SMS verification back to your home number
- Resume any services you suspended while abroad
Cancellation and suspension conditions and timing vary by plan, so checking your plan terms in advance gives you peace of mind. If you’re unsure about the order of steps, see the guide to restarting after you get home.

How to choose the right plan (your next step)
By now you may be wondering, “So how should I choose, in my case?” The three things that matter most in choosing a plan are your destination country, length of stay, and how you’ll use it. Making a comfortable choice based on those is the key to keeping it going long term.
The specifics of each plan (supported countries, data amounts, durations, compatible devices, and so on) vary by plan. We keep the latest details on the comparison page, so take a look there too. Pricing is in USD—please confirm the current price at the time of purchase.
