Top 10 Best eSIM Provider for 2025

Each type of SIM has its own advantages depending on the customer's usage needs. However, there are some outstanding advantages of eSIM compared to physical SIM cards: eSIM is the best choice for a travel SIM card in terms of security, because a physical SIM card can be removed from a lost or stolen phone. eSIM can provide higher security and safety. If, unfortunately, you lose or drop your mobile device, it would be difficult for malicious individuals to remove the eSIM from your device. Therefore, you can still contact your device or track it through 3G/4G signals or other methods. Secondly, both eSIM and physical SIM cards use the same mobile network profile, so in theory, there is no difference in service quality. Customers can use eSIM without worrying about losing signal, weak signal, or slow data access. At the current time, one eSIM can only be registered for one subscriber number. However, with the rapid development of telecommunications technology today, in the future, we can integrate up to 5 subscriber numbers for one eSIM, providing exceptional convenience and expandability for customers.

Currently, some phone models can still scan activation codes normally. But when users choose to enter the eSIM information manually, they report that the process cannot be done, even though the eSIM has never been activated. This issue often occurs with US Domestic devices, such as the Samsung S21 U.S. version. So, what can be done to tackle this problem? In this case, you need to enter the activation code with the following structure: 1$[SMDP address]$[activation code], instead of the normal activation code. After that, you can continue to add the eSIM normally. And that is how you can successfully set up eSIM manually on your device. If you still have any questions, please contact our customer support department for further information.

You cannot use eSIM if your phone is carrier locked. Please check the carrier lock status for each device as follows: For Apple devices: Go to [Settings] Choose [General] [About], and scroll down. If you find [Carrier Lock – No SIM Restrictions] and [Digital SIM – IMEI] (a series of numbers), then your phone is compatible with eSIM. If you see [SIM Restricted], then your phone does not support eSIM. For Samsung and Google devices: Navigate to [Settings] [Connections] [Mobile Networks] Select [Network Operators]. If multiple networks appear, your phone might be carrier unlocked. If only one result is returned from the network search or if the Network Search option is unavailable in the Network menu, your phone may be carrier locked. The only way to be sure if your phone is carrier unlocked is to review the current policy with your service provider.

When using a physical SIM card, it can take 2-4 days, depending on the geographical location, to receive the SIM card via shipping. But with eSIM, after a successful payment, you will receive the QR code within 5 minutes via email, providing convenience and optimizing both time and costs. Sometimes, the QR code sent to your email might end up in the spam or junk folder, so please make sure to check there. In case you do not receive the code, please contact our support team.

Each application will have a different data consumption rate. The amount of data you need to buy depends on how much time you spend using applications on your phone. Usually, social media and multimedia applications tend to consume the most mobile data (Facebook, Instagram, Snapchat, YouTube, and TikTok). If you tend to spend under 60 minutes per day on Facebook, TikTok, and Instagram, consider data packages with 1GB per day or less. If you spend 1 to 2 hours per day on Facebook, TikTok, and Instagram, choose data packages with 2GB per day or less. If you use even more than that, eSIM Travel recommends using Wi-Fi, or buying multiple high-data eSIMs, or data eSIMs that have no daily limits. When running out of data while abroad, you should consider buying a new international eSIM with the same data allowance. This is because topping up data while abroad is often expensive, usually more expensive than buying a new package

APN stands for Access Point Name, which is essentially the name for the settings that a phone uses to connect to the Internet.

All of the required information will have been sent to your email when you finished your order. If you are using an iPhone: Go to [Settings]. Select [Mobile] or [Cellular]. Choose [Mobile Data Options] You will see information such as APN, username, password. What you want to do now, is to manually enter the APN information.
