With the code CLUBIC, Saily offers a discounted unlimited eSIM plan for the United States, priced at 36.89 € for 15 days, instead of the regular 40.99 €. This offer is aimed at travelers heading to the U.S. for All Saints' Day, who want immediate data access upon arrival without relying on roaming from their French mobile plans. The CLUBIC code provides a 10% discount on the entire Saily catalog, reducing the cost of the 15-day unlimited plan to approximately 2.46 € per day. For stays lasting 17 days, the code also applies, lowering the cost of a 17-day plan from 45.49 € to 40.94 €. Saily, a travel-focused eSIM service from Nord Security (the publisher of NordVPN), offers data plans by destination through its website or app. For the United States, its unlimited plans are priced per day, with the 15-day version costing 40.99 €. The offer is especially useful for couples and families traveling for two weeks and wanting to know their data costs in advance. However, it may be less relevant for travelers whose existing French mobile plans already include generous data allowances in the U.S. The unlimited data plan allows users to consume up to 5 GB per day without speed restrictions, after which the connection is capped at 1 Mb/s. This daily reset means users can share data with devices like a laptop or tablet, within the 5 GB limit. The eSIM requires an internet connection to activate, ideally from home, and remains valid for 180 days from purchase. Network speeds vary from 3G to 5G, depending on local providers, though 5G is not always available, according to Saily's own evaluation. Beyond the 5 GB daily limit, the 1 Mb/s speed is sufficient for basic messaging but not for video streaming. This applies to other countries as well, such as Japan, where the 15-day unlimited plan drops from 43.49 € to 39.14 € with the CLUBIC code. The Saily eSIM provides only data, not a phone number or regular calling features, so users may need to rely on apps like WhatsApp or FaceTime, or opt for a paid American number at 0.99 € per month, along with a call plan and identity verification. In a comparison of the best international eSIMs, Saily ranks first for its price-quality ratio, while Holafly is noted for offering unlimited data at around 3.40 € per day. With the CLUBIC code, Saily’s plan drops to 2.46 € per day, with a daily 5 GB cap at full speed. Its strengths include adjustable duration, unrestricted data sharing, purchase up to 180 days in advance, automatic activation upon arrival, and features like virtual location and malicious site blocking. However, limitations include the 5 GB daily speed cap, no phone number or calling features unless paid for, the need for an eSIM-compatible smartphone, and the occasional absence of 5G. Those who rely heavily on video conferencing or need to make calls may find these limitations challenging. As a result, travelers should assess their data needs and adjust the plan duration to match their trip, a principle that also applies to other destinations like Japan.
