The short version: For stays of 30 days or more, the goal is to plan your connectivity so it never drops out. You have three main options: (1) use a single high-capacity plan, (2) renew or top up in stages, or (3) combine your eSIM with a local SIM. The key is to pick a little more data than you think you'll need, and to get your next plan ready before the current one runs out so the validity periods overlap slightly. A good starting point is our eSIM comparison page, where you can shortlist options by destination, data amount, and number of days. Plan details can change, so please check the latest information before you buy (accurate as of June 2026).
Three ways to handle an eSIM on a long stay
For a stay longer than a month, you can't just "buy one and forget it" the way you might for a short trip. Most eSIM plans come with a set number of usable days (a validity period), so it pays to think ahead about how you'll cover your entire stay. Here are the most common approaches.
| Approach | Who it suits | What to watch for |
|---|---|---|
| Use a single high-capacity plan | People who want fewer steps, or aren't comfortable with setup | You're meant to use it up within the validity period. If you run short partway through, you'll need to top up |
| Renew or top up in stages | People who can't predict their usage, or want to keep costs down | Don't forget to arrange the next one before it expires. You'll need to keep an eye on validity dates |
| Combine with a local SIM or plan | People who also need a phone number and SMS, or who are staying very long term | Some local plans require sign-up and ID verification after you arrive |
There's no single right answer — it depends on how long you're staying, how much data you use, and whether you need a phone number. If you're unsure, it helps to start with our guide to choosing a travel eSIM, which lays out the bigger picture and makes your own priorities easier to sort out.
How much data should you plan for? Think in top-ups
A common mistake on long stays is buying one big plan upfront and then spending the whole time wondering if it'll last. A better approach is to plan in smaller chunks and assume you'll top up as you go.
Set a rough monthly estimate
How much you need varies a lot with how you use your phone. As a very rough guide, if you mostly use maps, social media, and messaging, somewhere around 10–20GB a month is a reasonable starting point; if you stream video or make video calls daily, plan for more. Since the right number really depends on your habits, use the comparison page to weigh different data tiers and adjust.
Leave some headroom and top up when you run low
Rather than buying three months' worth all at once, it's usually more efficient to set up about a month with a little headroom, watch how fast it goes down, and add more as needed. With Bloomy, you can top up (add data to) the same eSIM when you're running low, up to a limited number of times. There's also an optional auto-charge feature that adds data automatically when you're running low — it's off by default, so only turn it on if you want it.
A tip for overlapping validity periods
The thing you most want to avoid with ongoing use is being offline for hours or days because your old plan expired before the next one was ready. The simplest way to prevent that is to let your validity periods overlap a little.
- Set up your second plan a few days before the first one runs out or expires
- Do the switch somewhere reliable, like a hotel or café with Wi-Fi
- Keep your QR code and setup details easy to reach from your account page so you can view them while abroad
How the validity period is counted (from the moment of purchase, or from when you first use the plan) varies from plan to plan. This matters even more on a long stay, so always check each plan's details before you buy.
Are unlimited plans a good fit for long stays? An honest look
If you'd rather not think about data at all, an unlimited-style plan can be a good option. That said, "unlimited" doesn't mean it's always at top speed no matter how much you use. Typically, speeds may be reduced after a certain amount of usage, and a fair-use policy (rules that keep the network comfortable for everyone) may apply. Whether tethering (using your phone as a Wi-Fi hotspot) is allowed also differs by plan.
On a long stay, where you tend to be online for hours at a time, these plans can be very convenient — just check the conditions in advance so there are no surprises. For how a premium unlimited plan is positioned and what conditions apply, see the Bloomy Unlimited Max page or the comparison page for the latest details (unlimited conditions are subject to change).
Planning around what a data-only eSIM can't do (phone numbers and SMS)
Most travel and long-stay eSIMs, Bloomy included, are data-only by design. You can use the internet and apps, but they generally don't include a phone number for voice calls or for receiving SMS. On a longer stay, there are times you'll need SMS verification or a phone number — for things like banking, government paperwork, or signing up for local services.
A few ways to cover this: use data-based calling apps such as WhatsApp, look into a service that lets you keep an existing number before you leave if that matters to you, or arrange a separate local plan that includes a number. Work out early whether you'll need a phone number, SMS, or voice calls, and it's worth also reading our guides on phone numbers and SMS. Keep in mind that whether you can keep a number or receive SMS verifications varies by provider and country and can change, so check official sources for the latest.
Common snags with ongoing use — and how to handle them
Make checking your data and expiry a habit
On a long stay it's easy to find yourself almost out of data without noticing. Check your remaining data and validity date now and then on your account page, and line up the next plan early.
If you lose connection, review your settings
If your connection suddenly drops, check airplane mode (toggle it off and on), your data roaming setting, and which line (plan) is selected. Problems sometimes appear after you restart your device midway through a long stay. Our troubleshooting guide walks through the steps.
Confirm your device is compatible first
None of this works if your device doesn't support eSIM in the first place. Check the compatible devices page ahead of time — including if you're planning to switch to a new device.
Find a long-stay plan with Bloomy
Bloomy is built around making things clear before and after purchase — whether it's your first time using an eSIM abroad or you're settling in for a long stay such as studying or working overseas. From the comparison page you can choose your destination, data amount, and number of days, and top-ups and auto-charge make ongoing use straightforward. If you want to get all your connectivity sorted before a long stay abroad, our guides by use case are a helpful reference.
Start by browsing options on the eSIM comparison page, and if anything's unclear, check our FAQ or reach out via Contact. Plan details, pricing, and supported countries can change, so please confirm the latest information before you buy (accurate as of June 2026).
