Cellesim

A global eSIM provider pairing data with built-in VPN

Cellesim is an eSIM retailer serving travelers with prepaid data plans across more than 200 countries. The service is sold through cellesim.com and includes a free VPN bundled with every eSIM purchase as a standard feature, differentiating it from competitors who charge separately for VPN access. The site emphasizes instant delivery and minimal roaming fees as core selling points. Cellesim maintains a Trustpilot presence for customer reviews, though the specific rating or review content is not captured here. The site does not specify who owns or operates Cellesim beyond this customer review presence, and provides no corporate information or founding date.

5G eSIMs priced individually by destination and region

Cellesim publishes pricing for individual countries and multi-country bundles, all emphasizing 5G access. For major travel destinations, prices begin at $1.84 for the United States, $3.49 for Japan and South Korea, $3.59 for Italy, France, Spain, Turkey, and South Korea, and $4.04 for the United Kingdom and Germany. Egypt costs $5.39; Mexico is $5.42; Brazil is $4.48. Belgium and Belgium are $3.59. City-specific 5G plans are available for major urban areas like New York, London, Rome, Paris, Osaka, Kyoto, Shanghai, and Beijing.

The site offers regional bundles for travelers covering multiple countries. Japan and South Korea together are $3.49. The United States and Canada combined are $4.49. Singapore, Malaysia, and Thailand are $3.49. Asia as a 7-country bundle costs $3.60. A larger 12-country Asia plan is $7.53. A 20-country Asia package is $12.00. Europe (unspecified country count in the pricing display) is $4.49. The Balkans (7 countries) are $5.16. The Caribbean (25 countries) is $19.67. Central Asia is $3.49. South America spanning 20 countries is $19.00. Africa covering 29 countries costs $12.49. All prices are shown in USD at checkout.

The site does not publish whether these are fixed data bundles, unlimited-data plans, or throttled-after limits. It also does not specify how long each plan remains valid or whether data expires after a certain period.

Coverage in 200+ destinations and 5G networks

Cellesim explicitly covers "200+ Countries" as shown on its homepage. The site lists destination pages for Italy, France, Mexico, Egypt, Turkey, the United Kingdom, Germany, Spain, South Korea, the United States, Brazil, and Belgium, plus city-specific pages for New York, London, Rome, Paris, Osaka, Kyoto, Shanghai, Beijing, Illinois, Georgia (USA), and Washington State. Regional bundles reach Asia, Europe, Africa, the Caribbean, South America, and the Balkans. However, the captured pages do not name the underlying mobile carriers or networks providing the 5G connectivity in each destination. The site states "5G" is included but provides no detail on network coverage depth or which carriers operate the service in specific countries.

Data-only with hotspot support and Wi-Fi installation

These are data-only eSIM plans without a phone number for standard voice calls or SMS. Customers can use internet-based calling and messaging apps, and WhatsApp can be kept active on their existing phone number through the eSIM's data connection. The site explicitly states, "You can keep using WhatsApp with your usual number over the eSIM's data connection. You don't need to register a new number." This is particularly useful for travelers who want to maintain their existing WhatsApp account without disruption.

Installation must be done over a reliable Wi-Fi connection before travel. Since eSIM profiles are digital downloads, having internet access before departure is essential. The eSIM must be unlocked from your home carrier and your phone must support eSIM technology. Device compatibility varies by exact phone model and regional version, and Cellesim provides a device compatibility page for checking before purchase. Travelers should verify compatibility before purchasing, as incompatibility is non-refundable based on the typical constraints of eSIM technology. Dual-SIM phones can use Cellesim's eSIM alongside your primary SIM card to avoid roaming charges on your home line. The site recommends turning off data roaming on the primary SIM to prevent accidental charges while using the eSIM for data.

The site mentions that customers can "share your connection with a hotspot" if both the plan and phone allow it, though no specific hotspot limits or caps are published. This means the eSIM can feed data to a laptop or tablet via tethering, but it is unclear whether all plans support this or whether there are separate hotspot allowances and restrictions. The activation process involves installing the eSIM and then following the plan's instructions for starting data roaming, which are separate steps. Support is available to help with setup or connection issues. The site notes that installing the eSIM does not always immediately start the plan; customers may need to manually activate it in their phone's settings or follow the plan's specific activation instructions to begin using the data.

Missing details on data limits, speed throttle, and carrier partnerships

Cellesim does not publish a throttle speed, fair-use data cap, or exactly how much high-speed data is included in each plan before throttling begins. It also does not clarify whether data expires after the plan duration or rolls over, or whether multiple activations are possible from a single purchase. The site names "5G" prominently but does not specify which mobile networks provide the service, making it impossible to know in advance which carriers you will connect to in each destination. The site offers city-level plans in addition to country plans for major cities like New York, London, Rome, and Paris, which may suit travelers on a tight geographic focus, but the value proposition compared to the corresponding country plan is not explained.

Top-up procedures are mentioned as potentially available through the Cellesim account or app, but no top-up pricing is shown and it is unclear whether top-ups extend validity or simply add additional data to an existing plan. No refund policy is provided on the captured pages. The site does not detail what happens if activation fails or if the eSIM simply does not work after installation, beyond the general instruction to contact support. The presence of device compatibility and detailed FAQs suggests the company anticipates setup issues, but the escalation path beyond support contact is not clear.

This service is best for travelers who own 5G-compatible, unlocked phones and prefer a straightforward, centralized purchase without needing to research individual carriers. The bundled VPN is a bonus for those concerned about public Wi-Fi security in certain destinations, and the availability of city-level plans adds flexibility for urban travelers who want to limit coverage to specific regions.
