eSIM Plans: Coverage in 200+ Destinations
While Yesim previously covered around 150 countries, they have massively expanded their coverage and now offer internet connection in over 200 destinations and regions. Whether you need a reliable eSIM for popular destinations like Egypt, Morocco, Tunisia, or the USA, or you’re looking for regional packages (Asia, Europe, etc.), their offering is fully sufficient.
We personally tested Yesim in Malaysia and Vietnam, where we needed a reliable mobile hotspot for work. During our usage, we experienced no issues whatsoever. The signal strength was purely dependent on the quality of the local network coverage.
SwitchLess Networks Technology: Yesim newly utilizes an automatic network switching technology. If local operator A only provides a 3G/LTE network, but operator B in your location has a 5G signal, Yesim will instantly and seamlessly switch you to the faster option, ensuring you always get the best possible connection.
Pricing Evaluation: How Does Yesim Compare?
Yesim is considered a highly attractive provider, even though it may not always be the absolute cheapest option on the market. For classic prepaid data packages (e.g., 1–10 GB), prices often hover at a similar level to Airalo. Unlimited data plans can be slightly more expensive in some countries, but you need to consider the broader context.
The true value of Yesim lies in its added services. When you factor in that you receive a premium VPN for free with every eSIM (a service you would normally pay a monthly subscription for), the price-to-performance ratio skyrockets. Furthermore, unique plans like the Unlim Day Pass and Pay & Fly guarantee that you won’t waste money on data you don’t actually use during your travels.

Overview of Plans: Standard, Unlimited, and Innovative
Yesim has significantly diversified its offering for 2026 to cover the needs of all types of travelers:
1. Standard Data Packages (Prepaid)
The classic offering of one-time data packages, usually ranging from 1 GB to 20 GB, valid for 7 to 30 days.
What stands out is the wide variety of unlimited data plans. However, our Yesim experience advises a bit of caution here. The data isn’t absolutely unlimited – a FUP (Fair Use Policy) applies. You receive 50 GB at full high speed, and after that limit is reached, you get an additional 5 GB at a reduced speed. For 99% of regular users, this provides total comfort, but it’s crucial to be aware of this threshold.
A major advantage remains that Yesim allows data sharing via Hotspot even on these unlimited packages, which is not a common practice among its competitors.
2. Unlim Day Pass (Unlimited Data by the Day)
This plan is an absolute game-changer for people who frequently take shorter trips. You don’t buy gigabytes; instead, you buy days with unlimited data (e.g., 10, 20, or 80 days).
- How it works: The package is valid for an entire year. A purchased day is only deducted from your account when you actually connect to a network abroad. It’s the perfect solution for weekend travelers.

3. Innovative Pay & Fly (Pay Only for What You Use)
A global plan covering over 170 countries that operates on a “Pay-as-you-go” principle. You load an initial credit (starting from $12) and pay purely for the megabytes you consume, based on the current pricing for that specific country. You no longer need to worry about buying a new eSIM every time you cross borders.
Yesim App: Purchase, Management, and Features
The Yesim app (available on the App Store and Google Play) is a core component of the user experience. It is modern, intuitive, and localized into multiple languages, making navigation effortless.
In-App Purchase Process:
- Registration: You can sign up using Apple ID, Google, Facebook, or your email.
- Selection: Search for your desired country or region. The app will display all available options (standard, unlimited, Day Pass).
- “Activate Later” Feature: Before completing the purchase, you can select the option to delay activation. You then have up to 12 months to initiate the plan, making it excellent for planning trips far in advance.
- Payment: Yesim offers an exceptionally wide range of payment methods. Besides traditional credit cards and Apple/Google Pay, you’ll also find PayPal and even crypto-wallet support (Binance Pay).
Furthermore, the app sends helpful push notifications to warn you about depleting data or the approaching expiration date of your plan.

Can I Share Data via Hotspot?
You can share all your data on Yesim using a personal hotspot. This rule applies to unlimited data plans as well. Just keep in mind that unlimited data is subject to a FUP (the 50 GB limit for 30 days, followed by 5 GB of slower data). Sharing your connection with other devices will naturally cause this high-speed allowance to deplete much faster.
Security Bonuses: Free VPN and Virtual Numbers
Free VPN with Every eSIM
This is a massive competitive advantage. With every data plan, you are granted access to an in-app VPN. Your traffic is fully encrypted, even if you are surfing the web on a public Wi-Fi network (like at a hotel or an airport). You can turn the VPN on with just one click inside the app.
It also allows you to bypass geo-restrictions and access websites that might be blocked in the country you are visiting. According to customer support, you are assigned a completely random IP address. Because of this, you might occasionally face issues accessing certain heavily localized websites. It happens rarely, but it’s good to know.
- Note: The VPN feature is currently only available for iOS devices (iPhone). Independent reviews often highlight this as a significant drawback for Android users.
Virtual Number
For a fee of approximately $3-4 per 30 days, you can rent a virtual phone number (options include USA, Canada, Netherlands, Israel). The number serves solely for receiving SMS messages. It is typically used for registering accounts on WhatsApp, Telegram, Tinder, or local food delivery apps where you prefer not to share your real, personal phone number.

Rewards: Loyalty Program (Ycoins) and Referral
Yesim boasts one of the most sophisticated and generous reward systems in the eSIM space:
1. Cashback and Ycoins
For every purchase you make on Yesim, you automatically receive 5% of the total amount back in the form of a virtual currency called Ycoins. These coins are credited to your account after the purchased plan expires. You can then use Ycoins to fully or partially pay for future data plans, or to top up your Pay & Fly global balance.
- Note: Ycoins are valid for 1 year from the date they are acquired.
2. Referral Program
The provider rewards you for recommending their services to your friends:
You can also earn extra Ycoins by reaching milestones based on the number of friends you successfully invite.
You will find your unique referral code inside the app.
When your friend uses this Yesim promo code during their first purchase (with a minimum value of €10 / ~$11), both of you will receive €5 in Ycoins.

Installation and Data Sharing (Hotspot)
Installation is standard: simply scan the QR code you receive via email or complete it with a single tap directly in the app. Important: Never delete an installed eSIM profile from your phone’s settings. If you delete it, you will be forced to buy a new one.
Hotspot: Unlike some competitors (for instance, Holafly often restricts data sharing on unlimited plans), Yesim allows you to tether your data even on their unlimited packages. Just be prepared for your 50 GB high-speed limit to deplete much faster when sharing across devices.
Customer Support and Money-Back Guarantee
This is where the most significant upgrade has occurred. Yesim has heavily invested in improving its customer service. While past user experiences (and reviews on sites like Simpackers) were full of complaints regarding slow support times (~5 hours), Yesim now confidently declares on its website: “24/7 Support, Average response time – just 6 minutes.” Support is accessible via in-app chat or email.
Money-Back Guarantee: Yesim now offers a 100% refund guarantee within 30 days of purchase for unused data plans. This is a powerful selling point that definitely provides peace of mind before making a purchase.
Final Verdict (Pros and Cons)
Yesim has made a massive leap forward in recent years, and its place at the top tier among authoritative data providers is well-deserved.

- ✅ Free VPN that works on both cellular data and Wi-Fi networks (iOS only).

- ❌ Despite the claimed 6-minute response time, real-human answers to complex technical questions can occasionally still take longer compared to the absolute market leaders.
Does the Yesim VPN work even when I’m connected to Wi-Fi?
Yes, the VPN in the Yesim app acts as a standalone client. It encrypts your internet traffic regardless of whether you are consuming your eSIM data allowance or connected to a public Wi-Fi network in a hotel.
Can I use my WhatsApp and other messengers with Yesim?
Absolutely. Your personal phone number for WhatsApp, Telegram, or Messenger remains fully active. The eSIM serves strictly as your source for internet connectivity.
When exactly does the validity of my data plan start?
The plan validity begins either upon installation and activation in your destination country, or when you consume your first bytes of data (depending on the specific plan type; for instance, the Unlim Day Pass only deducts a day after a successful network connection). Additionally, the app lets you delay activation for up to 12 months after purchase
Is the unlimited data truly unlimited?
Not completely. Yesim applies a 50 GB FUP (Fair Use Policy) limit. Up to this threshold, you enjoy the highest possible network speeds. After exceeding 50 GB, the connection speed will slow down. You can read more about unlimited data plans here.
