What is pocket Wi-Fi?
Pocket Wi-Fi, also commonly referred to as portable Wi-Fi or mobile hotspot, is a portable device that provides wireless internet access. It creates a hotspot, giving you access to an internet connection anywhere cellular coverage is available.
These devices are a go-to solution for travelers, offering an alternative to expensive and often unreliable international data roaming. A portable Wi-Fi router allows the user to connect multiple personal devices — smartphones, laptops, tablets — without relying on public Wi-Fi networks. They're also useful in areas with unstable or no fixed Wi-Fi connections.
How does pocket Wi-Fi work?
From a user's perspective, pocket Wi-Fi works much in the same way as a home router. Instead of being plugged into a fixed broadband connection, it uses mobile networks (4G or 5G) to create a private Wi-Fi network. This allows your other devices to connect to the internet just as they would at home.
The device needs a SIM card or eSIM to access mobile data, the same way your phone does. Once activated, the pocket Wi-Fi connects to the cellular network and creates a mobile hotspot that multiple devices can connect to. It has a network name and a password, like any other Wi-Fi spot.
Pocket Wi-Fi devices run on rechargeable batteries, which makes them great for internet access on the move. However, you'll need to keep an eye on battery life, especially during long days of heavy use.
How much does pocket Wi-Fi cost?
The cost of portable Wi-Fi depends on whether you're renting or buying the device and the amount of data you need. Here's an overview:
Device rental. Expect to pay $5–$10 per day, depending on the provider and the region. Some companies offer discounts for weekly or monthly rentals.
Device purchase. Buying a portable Wi-Fi router will cost you between $100 and $200 upfront. Remember, this is just for the device — you'll still need to purchase a data plan.
Data plans. Monthly plans for international use typically range from $20 to $50, depending on the amount of data and coverage area you need. Some providers also offer pay-as-you-go options or flexible plans tailored to specific regions.
Keep in mind that the total cost of using pocket Wi-Fi can add up quickly, especially if you're renting for a longer trip or need high-speed data in multiple countries.
Where to rent or buy pocket Wi-Fi
If pocket Wi-Fi feels right for your needs, you'll find plenty of options for renting or purchasing a device:
Rental. You can rent pocket Wi-Fi devices from airport kiosks, online rental services, and travel agencies. Many online providers allow you to reserve a device in advance and have it shipped to your home or hotel.
Purchase. Pocket Wi-Fi devices are available at electronics stores, specialized tech shops, and online retailers like Amazon.
Rent or buy pocket Wi-Fi: Which is the best option?
Choosing between renting and buying pocket Wi-Fi depends on how often you'll use it and the nature of your trips.
Renting is ideal for short-term trips (less than a month). It's less expensive upfront and doesn't require a long-term commitment.
Buying is better for frequent travelers who need portable internet regularly. While the initial cost is higher, buying will save money in the long run, especially if you look for affordable data plans.
Pros and cons of portable Wi-Fi
Portable Wi-Fi devices are a good way to stay connected to the internet, especially when you’re traveling across multiple destinations. However, like any technology, they come with strengths and weaknesses. Understanding both will help you decide if a portable Wi-Fi router is right for your needs.
Pros
Portable Wi-Fi has several key benefits that make it a popular choice for travelers and remote workers:
Reliable internet connection across multiple countries. With a single device, you can stay online in various regions without having to deal with local SIM cards or patchy mobile internet connection.
Internet connection for several devices. A mobile hotspot allows you to connect multiple devices simultaneously, with some portable Wi-Fi models allowing up to 10 or even 15 devices at a time.
No need to swap SIM cards or rely on public Wi-Fi. Say goodbye to hunting down local kiosks for prepaid cards or risking your data security on public Wi-Fi networks. With pocket Wi-Fi, you get a private, secure connection that works straight out of the box.
Cons
While portable Wi-Fi devices are convenient, they come with a few downsides that you should consider before committing:
The need to carry an extra device. Pocket Wi-Fi means one more gadget to keep track of during your travels. If you're trying to pack light, the added bulk — even if small — may feel unnecessary.
The need to manage battery life. Portable Wi-Fi devices run on rechargeable batteries, which typically last 6-12 hours, depending on usage. This means you'll need to carry a charger or power bank, especially during long trips or with multiple connected devices.
Costs adding up. Beyond the upfront cost of renting or buying the device, you'll need to pay for data plans, which can quickly add up for high-speed or international coverage.
Connectivity challenges in remote areas. Pocket Wi-Fi depends on cellular networks, so if you're in a remote location or a region with poor infrastructure, you may struggle to get a stable internet connection. Making video calls or sending large files will be no-go in such scenarios.
Less convenience than with eSIMs. Portable Wi-Fi requires carrying an extra device, keeping it charged, and often dealing with the logistics of renting or returning it. In contrast, eSIMs are integrated directly into your smartphone, offering instant activation and global coverage without the hassle of extra hardware.
Pocket Wi-Fi vs. local SIM card vs. eSIM: Which is the best for travel?
When choosing a travel internet solution, you'll need to weigh cost, convenience, and flexibility. Let’s see how pocket Wi-Fi compares to alternatives:
Feature | Pocket Wi-Fi | Local SIM card | eSIM |
---|---|---|---|
Cost | Moderate to high (device + data) | Low (SIM + local mobile internet plan) | Moderate (no extra device needed) |
Ease of use | Requires setup, charging, carrying | Requires finding a local store | Easy to activate online |
Coverage | Good in areas with cellular signal | Limited to one country | Global, depending on the plan |
Flexibility | Limited by device and data plans | Must swap SIM cards | Instant activation, multi-country |
eSIMs stand out as the best option for reliable internet access on the go. They are simple to activate, require no extra device, and allow you to top them up easily if you need more data. Plus, there's one eSIM for all destinations — switch between countries effortlessly. You can often use your smartphone as a mobile hotspot with an eSIM and connect different devices without a separate mobile router.
Best pocket Wi-Fi providers
If you've decided that portable Wi-Fi is the right option for your travel needs, the next step is choosing a provider. Here's a closer look at some of the most popular pocket Wi-Fi providers:
Skyroam is a widely recognized provider offering internet connection in over 130 countries. Skyroam devices are compact and easy to use, and they include a built-in power bank so that you don't need to worry about battery life.

When choosing a pocket Wi-Fi provider, think about where you're traveling, how many devices you'll need to connect, and the data limits offered by each provider.
How to set up and use pocket Wi-Fi
Setting up and using a portable Wi-Fi router is quick and simple. Follow these steps to get connected:
Insert a SIM card or activate the pre-installed eSIM if available.
Turn on the device. Press and hold the power button until the device powers up. Most devices have indicator lights or a small screen to show when they're ready to connect.
Connect your devices. Search for the Wi-Fi network name (SSID) and enter the password provided on the device. Many newer devices offer a QR code you can scan to connect instantly without typing the password.
Secure the connection. Change the default password to something more secure to make sure only authorized users can access the network.
Note: If you're traveling abroad, double-check your portable Wi-Fi settings. Turn off data roaming on the device to avoid unexpected charges unless your plan includes international roaming.
Do you really need pocket Wi-Fi?
While pocket Wi-Fi devices can be a good option, they’re often not the best one. Alternatives like eSIMs are more flexible, affordable, and convenient. The benefits of eSIMs allow you to skip the hassle of renting or buying devices, enjoy global coverage, and easily switch plans without visiting a local store. So, the next time you go abroad, download an eSIM to stay connected without the extra baggage.
