FAQs

Each phone model has a unique method to verify eSIM compatibility. To ensure your device is ready for eSIM, confirm it is both eSIM-compatible and carrier-unlocked.

Here are two ways to check if your device supports eSIM:

1. Click to quickly view eSIM Compatible Devices.

2. Dial *#06# and press call. If an EID number appears, your device supports eSIM.

With your eSIM, you can connect at 5G/LTF/4G/3G speeds, just like any local data line. However, in remote areas or places with poor coverage, your mobile might connect at lower speeds. Additionally, different data plans offer varying network speeds. You can find specific information in the Product Specs of each data package. Click to view detailed information about internet speed of your eSIM data plan, including detailed overview of different high-speed data options, and how to manage low-speed data under FUP limits.

Don’t worry. If you cannot find the code, please contact our customer support team service@microesim.com. We will resend you the code via email.

1. Open "Settings > General > About".

2. Scroll and look for Carrier Lock. Your iPhone is unlocked if No SIM restrictions appear next to Carrier Lock.

Here are two methods to check if your Android device is carrier-unlocked.  

1. Contact your Seller / Service Provider

• If you bought your phone directly from a manufacturer like Samsung, it's likely already unlocked.

• If your phone was bought from a telecom provider (e.g., Orange, AT&T, or Movistar), it may be restricted to their network. Contact the provider for confirmation. They can inform you whether your phone is network-locked and assist with unlocking it if necessary.

2. Use another SIM Card

• The simplest method to check your phone's status is to use a SIM card from a friend or family member.

• If you can successfully make a call or send a text with the borrowed SIM, your phone is unlocked.

• If you're unable to make calls or send texts using the new SIM card, this indicates that your phone is tied to your original provider and is not compatible with eSIMs.

Although traditional plastic SIM cards sometimes come with phone numbers, most eSIM cards primarily offer "data-only" services. This means that a data-only eSIM can provide the data needed for your device to connect to the internet but does not provide a phone number. However, you can still use the eSIM to make and receive calls.

Three ways to make phone calls with a data-only eSIM?

1. Use the internet

You can make calls using VoIP applications like WhatsApp, Zoom, FaceTime, and Skype, which use the internet for calls. If you're using an iPhone or iPad, you can also use iMessage and FaceTime. When using these services, ensure that data roaming is turned off for your primary SIM card, so your device only uses the eSIM for data.

2. Use social media platforms

If you have a Facebook account, you can easily make video calls through Messenger. You can also use the calling feature in Instagram's direct messages (DMs) to communicate with contacts. Again, make sure data roaming is turned off for your primary SIM card to avoid incurring roaming charges.

3. Use your primary phone number

If you have the eSIM set up for local data while traveling, you can still keep your regular phone number fully functional. As eSIM data is prepaid, you won't incur any data roaming charges. Note that data usage is different from voice calls/text messages. Your carrier will charge you on a per-use basis for any valid calls or text messages made while in other countries/regions.

How to use your phone number with a data-only eSIM?

1. Keep your primary SIM card active so you can use your regular phone number.

2. Turn off data roaming for your primary SIM card to prevent it from using data.

3. Confirm that you are not enrolled in a travel plan with your carrier.

4. Select your eSIM as the data source for your phone to use the eSIM for all mobile data transmissions.

5. Expect charges from your carrier for active voice calls and text messages.

When using an eSIM for all your mobile data, your home carrier cannot charge you for data roaming. However, they still own your phone number, so they can bill you for individual voice calls and text messages when you are abroad. The charges may vary depending on your carrier and the destination.

How much does it cost to make phone calls with a data-only eSIM?

Because you have wisely turned off data roaming for your primary SIM card to avoid roaming charges and confirmed that you don't have a carrier travel data plan, your local carrier cannot charge you for data usage. However, if they still allow you to use their network for phone calls with your phone number, they can charge you for personal voice calls and text messages. Here are three common scenarios:

（1）If a call comes in but you don't answer, you won't be charged.

（2）If you decide to answer or make calls, your regular phone provider may charge you per minute, and these additional charges will appear on your next bill.

（3）If you only make or receive occasional calls, the charges may be relatively low, but it's best to check with your carrier's rates before traveling.

How much does it cost to send text messages with a data-only eSIM?

Typically, there is a cost associated with sending or receiving SMS text messages, with the cost per message ranging from 50 cents to a couple of dollars. However, some carriers may offer free texting services, so you won't be charged for received messages even while traveling internationally. Keep in mind that if your settings are configured correctly, messages sent via iMessage won't be treated as SMS because these messages are sent between Apple devices via the internet (either Wi-Fi or data).

There is no need to delete the eSIM once you have finished using it. However, if you wanted to, you can do this by going to your phone’s SIM card manager.

Your eSIM can only be activated on one device. If you delete the eSIM from your device, you will not be able to reuse it. You cannot scan the QR code on two devices. However, you can share data with another device by setting up a mobile hotspot from your cell phone.

The eSIM is a digital product. Therefore, refunds will be provided under certain circumstances.

For more information, please check our Refund Policy.

After payment, your eSIM will be sent to the email address you entered during the purchase process. To avoid delaying your journey, please make sure you enter the correct email address.

Typically, to set up an eSIM, you need to add/install the eSIM to your device while connected to Wi-Fi and then activate the eSIM. We recommend you print the QR code and take it with you just in case.

• Please install/add your eSIM plan one day prior to your departure and activate the data plan and data roaming upon arrival at your destination.

• If you are at your destination, you can add the plan any time you want. The eSIM data plan will be activated once you connect to the local network.

• The setup process may vary from different devices. For more details, please click to see how to install eSIM.

The days start counting when you activate data roaming on your cellphone. Therefore, the number of days in the plan will start counting down when you activate the eSIM, not when you install it.

Sorry, you cannot. When you use your phone to scan the QR code for the first time, the binding has been established, and other phones cannot no longer scan and use the QR code. In addition, One QR code cannot be scanned multiple times, and the scan will not work if the number of scans exceeds the limits.

Yes, you will keep your WhatsApp number with all your conversations and contacts. You can still use it just like normal.

• For iPhone users, services such as iMessage and Facetime are also accessible via our eSIM.

• In the event that you need to receive text messages from your bank, for instance, for cash withdrawal purposes, we suggest you get in touch with your bank. They can arrange for these messages to be delivered to your email address, ensuring you don't miss any important notifications.

At the moment, you cannot renew the data on your eSIM. However, you can purchase another eSIM if you need more data.

True Unlimited Data Plans: These plans offer truly unlimited high-speed data without any specific data cap. However, in accordance with Fair Usage Policy (FUP) guidelines, which vary by destination and operator, data usage might be monitored. Operators reserve the right to limit data traffic for users who consume large amounts of data in a short period of time. Typically, usage above 10GB in a single day may result in speed throttling, which resets daily.

Unlimited Data Plans with High-Speed Data Cap: These plans come with a predefined amount of high-speed data. Once you've used the allocated high-speed data, you can still enjoy unlimited data access at a reduced speed of 128kbps. This ensures you're always connected, even after heavy usage.

Usage Recommendations: To get the most out of your unlimited data plan, we recommend moderate usage and avoid consuming large amounts of data in a short period of time, such as extended video viewing or heavy data downloads. This helps avoid temporary speed throttling and ensures a smooth online experience.
