Every trip abroad ends up raising the same question: how will you get online once you land? In 2026 there are three realistic options for most travelers — an eSIM, a pocket WiFi router, or a local SIM card. Each one wins in a different situation, and choosing badly means either overpaying or being stuck without a signal when you need it most. Here is a practical comparison to help you decide.
The three options at a glance
A local SIM card is bought at your destination and gives you cheap local data. An eSIM is a digital SIM you buy online and activate instantly on a compatible phone. A pocket WiFi router is a small device that carries its own data plan and shares a private connection with several devices at once. The right choice depends on how many devices you carry, how many countries you visit, and how much hassle you are willing to accept.
Local SIM card: cheapest per gigabyte, most friction
If you are staying in a single country for a while and you only need to connect one phone, a local SIM is often the cheapest option per gigabyte. The downsides are real, though: you need an unlocked, SIM-free phone, you usually have to show your passport at a shop, you lose your normal phone number while the SIM is in, and you have to repeat the whole process in every new country. For a multi-country trip it quickly becomes tedious.
eSIM: convenient, but with limits
An eSIM is genuinely convenient — you buy it before you leave and it activates in minutes, with no physical card to swap. But there are two catches. First, only recent phones support eSIM, and each eSIM connects a single device. Second, many regional eSIM packages quietly exclude the exact countries where roaming gets expensive — Switzerland, the UK, parts of the Balkans — so you need to read the coverage list carefully before buying.
Pocket WiFi: one connection for everything
A pocket WiFi router takes a different approach: instead of connecting one phone, it creates your own private hotspot that several devices share at once. That makes it the natural pick when you travel with a laptop, when there is more than one person in your group, or when your trip crosses several borders. A device like the Ryoko pocket WiFi router covers 176 countries and connects up to 10 devices on a single 4G connection — phones, laptops and your travel companions’ devices all at the same time, with no SIM swapping and no new contract each time you cross a border.

So which one should you pick?
As a rough rule: choose a local SIM if you are a solo traveler staying in one country and you want the lowest possible price. Choose an eSIM if you travel light with a single recent phone and your destination is fully covered. Choose a pocket WiFi router if you carry several devices, travel with others, or move between countries — the convenience of one always-on private connection usually outweighs the small daily cost.
Frequently asked questions
Can I use a pocket WiFi and an eSIM together? Yes. Many travelers keep an eSIM as a backup for their phone and rely on a pocket WiFi router as the main connection for all their devices.
Does a pocket WiFi work across several countries? Yes — that is its main advantage. A single device like Ryoko keeps the same connection as you cross borders, with no need to buy a new SIM or plan each time.
Is an eSIM always cheaper than pocket WiFi? Not necessarily. For one device it can be, but once you are connecting a laptop and several phones, a single shared connection is often better value than several separate eSIMs.
