When you’re planning to live abroad for months—not just a two-week holiday—the eSIM versus physical SIM question gets more complicated. We ship connectivity to digital nomads doing 3-month Southeast Asia loops, van lifers crossing a dozen European borders, and remote workers splitting time between Lisbon, Barcelona, and Marrakech. Here’s what we’ve learned about what actually works when “long-term” means constantly moving.

Why This Decision Matters More for Multi-Country Long-Term Travel

If you’re spending six months in one country, the answer is simple: buy a local physical SIM card when you arrive, top it up monthly, and you’re done. Local carriers in Spain, Thailand, Portugal, or Mexico offer excellent value when you stay put.

The real question comes up when your “long-term travel” looks like this: two months in France, three weeks in Spain, a month in Portugal, back to the UK for a few weeks, then off to Turkey. Or the classic digital nomad pattern of moving cities every 4-6 weeks. That’s when the constant SIM-swapping, the hunt for a phone shop every time you cross a border, and the leftover data you can’t use anymore become genuinely annoying.

“We managed to stay always connected while travelling around Europe, without having to buy SIM cards in every country and ending up with a handful of them with different balances we couldn’t use. Excellent support team.”

eSIM for Long-Term Travel: The Convenience Case

An eSIM is a digital SIM card built into your phone. You buy a data plan online, scan a QR code, and you’re connected—no physical card to insert.

For long-term travellers moving between countries, the appeal is obvious: you can switch plans without finding a shop, you can stack multiple eSIM profiles (keep your home number active, add a local data eSIM), and you never lose a tiny piece of plastic in a hostel in Chiang Mai.

The trade-off? Price. Most eSIM providers charge a premium because they’re selling convenience to tourists. A 30-day eSIM for Spain might cost €25-35 for 10GB, while a physical SIM from Orange or Vodafone Spain gives you 50GB for €15/month. Over six months across four countries, that difference adds up.

eSIMs work well if you’re changing countries every 1-2 weeks and value not having to research local carriers in every new place. They work less well if you’re staying a full month or longer per country and have time to walk into a shop.

Physical SIM Cards for Long-Term Travel: Still the Budget Winner

If your long-term trip involves staying in each country long enough to make it worth the effort, local physical SIM cards are still unbeatable on price. In Portugal, you can get 100GB/month for under €10. In Thailand, unlimited data plans run about 600 baht (roughly €15). In France, Free Mobile offers 210GB for €19.99/month with no contract.

The downsides are real, though. You need to find a phone shop (often at the airport, sometimes requiring a trip into town). You’ll need ID, sometimes proof of address. Topping up can mean navigating an app in a language you don’t speak. And every time you move countries, you start over—new SIM, new phone number, new setup process.

For van lifers doing a slow lap of Europe, buying a French SIM, a Spanish SIM, and a Portuguese SIM separately makes sense if you’re spending 2+ months in each. For someone doing the European capital city circuit every few weeks, it becomes exhausting.

Home Carrier Roaming: The Expensive Fallback

Some travellers just leave their home SIM active and pay roaming charges. If you’re from the UK and roaming in the EU used to be free, but most carriers now add daily fees (£2-3/day) or cap your included data abroad. Over a month, that’s £60-90 just to use what you already pay for at home.

US carriers are even worse—AT&T and Verizon charge $10/day for international roaming in most countries. Over 90 days, that’s $900 for connectivity you could get locally for a tenth of that.

Roaming makes sense for a week-long trip where you don’t want to think about it. For long-term travel, it’s the most expensive option by far.

The Monthly Subscription Alternative: When You’re Moving Often

Here’s the option most generic eSIM guides don’t mention: monthly connectivity subscriptions designed specifically for people who move between countries regularly.

ConnectPls, for example, is a monthly subscription that works across 160+ countries. You activate it for the months you’re travelling, pause it when you’re not. It’s available as an eSIM, a physical SIM card, or a portable WiFi device (which is included in the monthly plan and shipped to you—no upfront hardware purchase).

The Plus Europe package is truly unlimited (no throttling after daily caps) across about 70 countries including the UK, Ireland, France, Germany, Spain, Italy, Portugal, Netherlands, the Nordics, Turkey, Canada, Mexico, Australia, and New Zealand. If you’re a digital nomad doing a European road trip or splitting time between southern Europe and North Africa, you cross borders without changing SIMs or buying new eSIM plans every time.

For countries like Japan, Thailand, China, and Singapore, there’s unlimited data but it may slow after about 5GB per day (still 4G, just throttled). For places like Brazil, Egypt, or Morocco, you get 500MB/day at full 4G speed, then 256kbps.

The device-included portable WiFi option is popular with van lifers because it connects up to 10 devices at once—your laptop, phone, partner’s phone, tablet all share one data connection. It uses Cloud SIM technology (automatically switches between local operators) plus a backup physical SIM slot, so you’re not stuck if one network has a bad day.

Delivery is 2-3 working days across Europe, 4-5 days in the UK. Billing is monthly with no long-term contract—you cancel anytime (there’s a £25 fee only if you cancel a mobile router subscription within the first 3 months, which covers the shipping and return logistics).

Real Scenarios: What Works When

Three months in one country: Buy a local physical SIM. It’s the cheapest and you have time to set it up properly.

Changing countries every 2-3 weeks: A monthly eSIM or portable WiFi subscription saves you the constant SIM-hunting. You pay a bit more than local SIMs but far less than buying a new tourist eSIM in every country.

Van life across Europe for 6+ months: A portable WiFi subscription (like ConnectPls Plus Europe) means one bill, no border hassles, and you can run Zoom calls from a campsite in the Pyrenees or a Portuguese beach car park without finding WiFi.

Mix of long stays and short hops: Use a local SIM where you’re staying a month or more, and a travel eSIM or subscription for the in-between countries.

Comparison: eSIM vs Physical SIM vs Roaming vs Portable WiFi

Option	Best For	Typical Monthly Cost	Setup Effort	Multi-Country Use
Local Physical SIM	Staying 1+ months per country	€10-20/month	Medium (find shop, ID required)	New SIM each country
Tourist eSIM (single-country)	Short trips, 1-2 weeks	€25-35 for 30 days	Low (buy online, scan QR)	Buy new plan each country
Home Carrier Roaming	Week-long holidays	£60-90/month (UK), $300+/month (US)	None (just use your phone)	Works everywhere, very expensive
Monthly eSIM/WiFi Subscription	Multi-country, frequent movers	Varies by provider and region	Low (activate once, works across countries)	One plan, many countries

What About Portable WiFi for Long-Term Travel?

Portable WiFi deserves its own mention because it solves a problem eSIMs and SIM cards don’t: connecting multiple devices without tethering.

If you’re a digital nomad working from your laptop, a van lifer with a partner who also needs connectivity, or someone who uses a tablet, phone, and laptop daily, tethering your phone gets old fast. It drains your phone battery, and if you’re on a video call on your laptop, you can’t easily use your phone at the same time.

A portable WiFi device creates a dedicated hotspot. ConnectPls ships the device as part of the monthly subscription (it’s included, not purchased separately), and it connects up to 10 devices. For couples travelling together or anyone working remotely, it’s one data connection that everyone shares.

It’s also useful in places where you need a backup. In rural Spain or remote Scotland, having Cloud SIM (which switches between multiple operators automatically) plus a backup physical SIM slot means if one network is patchy, you’ve got options.

Frequently Asked Questions

Can I use the same eSIM across multiple countries for months?

It depends on the eSIM. Single-country tourist eSIMs expire after 7-30 days and don’t work elsewhere. Multi-country or regional eSIMs (like Europe-wide plans) work across multiple countries but often have data caps and limited validity periods. Monthly eSIM subscriptions designed for long-term travellers let you stay connected across many countries as long as your subscription is active, without buying a new plan at every border.

Is portable WiFi cheaper than buying local SIMs in every country?

If you’re staying 2+ months in one country, a local SIM is almost always cheaper. If you’re changing countries every few weeks, a portable WiFi subscription can work out similar in price or even cheaper than constantly buying new SIMs or tourist eSIMs, and it saves you the hassle of setting up new accounts in every country. It’s about convenience versus absolute lowest cost.

Do I need a local bank account or address to get connectivity for long-term travel?

Local physical SIMs sometimes ask for proof of address (especially in France or Germany), though tourist SIM counters at airports are usually more relaxed. eSIMs and subscription services like ConnectPls don’t require local bank accounts or addresses—you pay with your regular card, the device or eSIM profile ships or activates wherever you are, and billing is monthly without needing to open a Spanish bank account when you’re only there for six weeks.
