If you're traveling and need the Internet on multiple devices – like your phone, laptop, or tablet – there are two easy options: rent or buy a portable Wi-Fi device, or use your phone’s hotspot option with an eSIM. In this guide, we’ll compare both and show you how to turn your phone into a pocket Wi-Fi so you can stay connected with fast 4G or 5G wherever you go.
How to Use the Internet on Multiple Gadgets While Traveling?
The first option is to use portable Wi-Fi, also known as pocket Wi-Fi. You can either buy one or rent it once you arrive in a new country. What is portable Wi-Fi for travel? It’s a compact device that connects to the internet via a SIM card and shares the connection over Wi-Fi, offering 3G, 4G, or 5G access
Alternatively, you can buy a travel eSIM and use your smartphone as a pocket Wi-Fi thanks to the sharing option (”Hotspot”). This lets you share the Internet with your other devices or with friends you're traveling with – a smart way to save money when you're on a trip with others.
Pros and Cons of eSIM vs Portable Wi-Fi
Comparison of both options – in a table.
| Criterion | eSIM | Portable Wi-Fi |
| Ease of Activation | Very easy: You can purchase an eSIM online in just a few clicks and have internet on all your devices as soon as you arrive in a new country by using your phone’s internet sharing feature. | Moderate: You’ll need to find a local mobile provider in the country you’re visiting, pick a suitable data plan, and buy a local SIM card to use with your device. |
| Number of Connected Devices | Supports 5 to 10 devices (depends on your phone’s brand and model – iPhone, Samsung, etc.) | Supports 5 to 15 devices (varies by model) |
| Internet Speed & Stability | Offers high-quality service and extensive coverage across the country because the eSIM provider partners with multiple local networks. You can even switch to a different network if the signal weakens. | Coverage depends on the local operator you choose. However, there’s a higher risk of poor signal – especially in remote areas – since you’re limited to a single provider’s network. |
| Cost | Budget-friendly: You only pay for the data plan for a specific country or region, with basic packages starting at around $2.15. | Moderate cost: You’ll need to buy an additional device (or rent one in the new country, which is usually more expensive) + local SIM card and a data plan. |
| Battery Life During Continuous Hotspot Use | Depends on the smartphone model, averaging around 4 to 6 hours. The advantage is easier control + charging only one device. ** To extend continuous hotspot usage, it’s recommended to use a power bank. | On average, battery life ranges from 4 to 10 hours, with more expensive devices typically lasting longer. |
How to Make Your Smartphone Work as a Pocket Wi-Fi
You can purchase an eSIM and turn your smartphone into a pocket Wi-Fi without needing any additional devices. Here’s how to do it:
- Choose a data plan on the PrimaSIM website or app and buy your eSIM online.
- Activate the eSIM – a detailed guide is available here.
- Enable the Hotspot feature:
On iPhone: open «Settings», go to «Cellular», select «Personal Hotspot», and toggle «Allow Others to Join».
On Android: open «Settings», then «Network & Internet», select «Hotspot & Tethering», and turn on «Wi-Fi Hotspot». - (Optional) Set a network name (SSID) and password.
- Connect your other devices via Wi-Fi.
Conclusion: Which is More Convenient?
Using an eSIM and your smartphone as a pocket Wi-Fi is a more budget-friendly option since you don’t need to buy any additional devices. Travel plans often cost about the same as local SIM plans, and can sometimes be cheaper. Additionally, setting up internet access with a virtual SIM is fast and straightforward – you can purchase it online and have connectivity immediately upon arrival at the airport.
