While it doesn’t offer voice or SMS, its competitive pricing makes it one of the most attractive options for short-term or regional travel. Plans can be purchased and activated directly through the app, which also allows you to monitor data usage and top up as needed.

The platform also runs occasional discounts and seasonal promotions, further enhancing its value. For anyone traveling to Europe, Asia, or North America, Nomad is an excellent choice for staying connected on the go without overspending.

3. Holafly

Holafly is a powerful option for heavy data users who want to enjoy unlimited internet during international travel. Available in more than 160 destinations, Holafly provides both eSIM and physical SIM cards, depending on your device preference.

It’s especially popular among digital nomads, content creators, and remote workers who rely on uninterrupted data access for video streaming, cloud storage, and Zoom calls.

For travelers who need both voice and text in addition to mobile data, OneSimCard offers a dependable physical SIM solution. Covering over 200 countries, this SIM card is ideal for business travelers, seniors, or users visiting regions with spotty Wi-Fi. Unlike most eSIM providers, OneSimCard includes traditional call and SMS functionality, which is useful in areas where internet-based communication isn’t reliable.

The SIM supports dual-SIM and unlocked phones, allowing travelers to keep their home number active while using OneSimCard for international access. However, activation involves physical insertion and may require manual APN settings, making it slightly more complex than eSIM alternatives. Data pricing can also be higher compared to digital-first providers.

Still, if you’re looking for a comprehensive travel SIM that supports multiple services and offers global reach, OneSimCard remains a classic and dependable option.

5. SimOptions

SimOptions operates as a global travel SIM marketplace, offering both eSIMs and physical SIM cards from top international carriers like Orange, Three UK, and AIS.

GigSky is ideal for travelers who rely on Apple’s ecosystem and want a plug-and-play mobile data solution for international use. While its plans are slightly more expensive than some competitors, they offer consistent performance and quality service. Like many eSIM providers, GigSky’s plans are data-only, so voice and SMS features must be handled via third-party apps.

The brand also provides customer service through the app, making it easy to resolve issues while on the road. For seamless connectivity that plays nicely with Apple products, GigSky is one of the best international eSIM choices in 2025.

7. KeepGo

KeepGo takes a different approach by offering reusable, refillable SIM and eSIM cards designed for long-term travelers and frequent flyers. Once you buy a KeepGo SIM, you can keep it active indefinitely as long as you top up data at least once every 12 months. This makes it highly cost-effective for business professionals or digital nomads who travel several times a year.

KeepGo supports over 100 countries and is known for its solid network reliability and consistent speeds. The service is data-only, so it won’t suit users who require traditional voice or SMS services. The price per GB may be slightly higher for light users, but the long-term value and convenience of using the same SIM for multiple trips outweigh this for frequent travelers.

Activation is straightforward, with a web-based dashboard that lets you manage data, purchase add-ons, and monitor usage. For long-haul connectivity without swapping SIMs every trip, KeepGo is an excellent investment.

8. TrueMove H

TrueMove H is a Thailand-based mobile provider offering excellent eSIM and SIM options for travelers in Southeast Asia. It’s particularly popular among tourists heading to Thailand, Vietnam, Laos, and Malaysia due to its competitive pricing and solid regional coverage. Plans are available for short stays or longer visits, and many include generous data bundles at low prices.

While the primary market is Thailand, many of the travel SIMs offered by TrueMove H include roaming coverage in neighboring countries, making it a strong regional player. Some plans may require initial activation within Thailand, so travelers should confirm roaming capabilities and purchase terms in advance.

The provider offers both English and Thai language support and provides basic setup instructions online. With fast speeds, low latency, and wide regional access, TrueMove H is one of the best SIM card options for anyone exploring Southeast Asia in 2025.

9. Orange Holiday Europe SIM

The Orange Holiday Europe SIM card is a reliable physical SIM option tailored specifically for travelers visiting multiple countries within the European Union. It offers up to 20GB of high-speed data, unlimited calls and texts within Europe, and a valid usage period of 14 to 28 days depending on the plan.

This SIM card works seamlessly across 30+ EU nations, making it ideal for those traveling by train or car through multiple borders. Provided by Orange France, it benefits from excellent network quality and widespread coverage. However, being a physical SIM, it requires delivery before your trip and needs an unlocked phone with a SIM slot.

It’s not compatible with eSIM-only devices such as some U.S. iPhone models. For travelers focused exclusively on European destinations and needing both data and voice functionality, the Orange Holiday Europe SIM is one of the best travel SIM options available.

10. T-Mobile Prepaid SIM

The T-Mobile Prepaid SIM is a go-to choice for travelers visiting the United States, Mexico, and Canada. Offering full 5G and 4G LTE data, unlimited talk and text, and solid coverage across North America, this physical SIM is well-suited for business travelers, families, and tourists alike.

One of its biggest advantages is the inclusion of free roaming across Canada and Mexico, which removes the hassle of switching SIMs while crossing borders. You must activate the SIM in the United States, and you’ll need an unlocked device with a SIM slot. Plans start at around $30 and can be purchased online or in T-Mobile retail stores.

While not ideal for destinations outside North America, it’s arguably the best SIM for use across the U.S. and its neighboring countries.
