Will my original LINE chat history or other account settings be lost when I use a SIM card?
No, using a data SIM card or eSIM will not affect the original apps on your phone. Data and chat history from LINE, Facebook, WeChat, or other communication software will still be there and will not be logged out!
Will I be charged extra for enabling data roaming?
Will I be charged extra for enabling data roaming?
No, using our data SIM card or eSIM to enable data roaming will not incur any extra charges, so you can rest assured!
If you are worried about making a mistake, you can remove the Taiwan SIM card, and with eSIM you can turn off the Taiwan mobile plan.
Can I receive calls and text messages from Taiwan while abroad?
Can I receive calls and text messages from Taiwan while abroad?
If you need voice or SMS services while abroad, please contact your Taiwan mobile number provider to activate roaming service for your Taiwan number. You will then be able to receive calls and SMS messages from Taiwan while abroad. 👉Roaming fees are subject to the rates announced by each mobile number provider.
Does the SIM card/eSIM itself provide a mobile number?
Does the SIM card/eSIM itself provide a mobile number?
Our product descriptions detail all product features; please read them carefully. Some products that come with a free mobile number only support local calls and cannot make international calls.
Can the phone number included with the product be used to register an account?
Can the phone number included with the product be used to register an account?
The SIM cards/eSIM products we sell will be reused by the telecom operators after the number is used up! Just like in Taiwan, when you give up your number, the telecom operator will reclaim the number and transfer it to the next user. Therefore, we cannot guarantee that the number will be able to successfully register an account for a local app.
Since we don't primarily sell mobile phone numbers, we cannot offer refunds if you encounter registration problems. If your main purpose is to register an account, we recommend that you tell your needs when you go to your local telecom store to apply for a number.
What is a native SIM card?
What is a native SIM card?
Native SIM cards are SIM cards directly provided by local telecommunications operators (such as China Mobile, NTT Docomo in Japan, and AT&T in the United States). Compared with roaming or international SIM cards, their operation and service are entirely based on the local network of the region, so the reception is relatively stable and they have network priority.
What is the Fair Use Principle (FUP)?
What is the Fair Use Principle (FUP)?
In other countries, "unlimited data" internet is called "eat to your heart's content," while in Taiwan it's called "eat to your heart's content." However, the meaning of "unlimited data" internet abroad differs from that in Taiwan; overseas telecom operators are less likely to offer unlimited data plans like they do in Taiwan.
Because network bandwidth is a limited resource, it is not unlimited.
Therefore, the telecommunications company's Fair Usage Policy is designed to ensure that all users can use network services fairly and reasonably, and to prevent excessive use by a few from affecting others.
If a user outputs a large amount of data in a short period of time, such as by sharing hotspots or live streaming, it is likely to be identified as abnormal usage and their network speed will be reduced or their network will be disconnected to protect network stability and prevent resource abuse.
What should I do if I can't access the internet while abroad?
What should I do if I can't access the internet while abroad?
If you find you cannot connect to the internet after inserting your SIM card/installing your eSIM upon arrival, please remain calm and try connecting to airport or public Wi-Fi. We can provide contact information for our official LINE customer service on our product packaging and website. Our team consists of trained professionals who will assist you in checking and adjusting settings as soon as possible to help restore your network connection.

What can you do after reducing the speed to 128kbps?
What can you do after reducing the speed to 128kbps?
When the network speed drops to 128Kbps, the speed is very limited. You can use text messaging to send messages and browse emails. Web browsing is limited to plain text content. If there are images or multimedia websites, it may be very slow or even fail to load at all, and it will take much longer!
How can I check my data usage?
How can I check my data usage?
Depending on the phone brand and operating system, the interface for querying on the phone will vary. The following example uses the iPhone (iOS) system:
1. Go to [Settings]
2. After selecting "Mobile Services", the bottom of the screen will display "< Current Mobile Data Usage During the Period >". Scroll down to see the data usage of each app.
(Data is for reference only.) For a clear and accurate usage amount, please contact our official customer service for assistance!
How long can 1GB last?

What is a card locking machine?
A SIM-locked phone is a mobile phone that can only use a specific telecom SIM card and cannot use SIM cards from other telecom companies.

Can FaceTime still be used after using a SIM card?
Basically, FaceTime can be used as long as there is an internet connection. However, it is uncertain whether changing your SIM card will restrict your account usage. To confirm that you can use FaceTime, it is recommended that you go to your local internet service provider and tell them your needs.

How should the number of days a product is used be calculated?
Our SIM card counts the time from the moment it's inserted until midnight, based on Taiwan time . The native SIM card, on the other hand, counts the time based on local time.
👉This rule does not apply to some products or activation cards in certain special regions. Please see the product description or contact customer service for details!
Which mobile phone models are compatible with this SIM card?
Which mobile phone models are compatible with this SIM card?
Our SIM cards are compatible with most standard mobile devices, but please note that activation may be difficult for the following specific models, and therefore we do not recommend using our SIM cards:
Please note that the following devices are not compatible with our products:
• Phones that can be used for internet sharing, counterfeit phones, tablets • Asia-Pacific phones, customized phones (fake phones), phones with locked SIM cards • Sharp • Google Pixel 8 and 8 Pro (and above) • Sony Xperia series • Smartphones released before 2019 <br/>If you have any of the above models, it is recommended to bring a spare phone or activate roaming service directly with your telecom operator for safety!
Can it be used with a dual-SIM phone?
Can it be used with a dual-SIM phone?
With a dual-SIM phone, you can try using both SIM cards simultaneously. However, if the two cards interfere with each other's signal, you'll need to put the network card in SIM slot 1 and leave SIM slot 2 empty. In most dual-SIM phones, when using two cards simultaneously, one of the cards will drop to a 2G signal. Since many telecom companies no longer provide 2G service, inserting a card in this slot will render the phone unusable.
We've also encountered situations where using two SIM cards simultaneously only results in a maximum connection speed of 3G. To avoid impacting network quality, in such cases, we recommend placing the network card in SIM slot 1 and leaving SIM slot 2 empty . If using both SIM slots simultaneously doesn't affect network reception, then you can use both slots at the same time.
Can the network card be used on a tablet or a sharing device?
Can the network card be used on a tablet or a sharing device?
Our network cards are designed for mobile phones. We cannot guarantee that they will work on devices other than mobile phones. In our past experience, some customers have had trouble connecting to the internet on other devices no matter how they configured them. They eventually had to switch them back to their mobile phones to get the network working.
If you need our assistance in checking the settings, you'll need to put the network card into your mobile device before we can help you.
Can I insert my SIM card in advance in Taiwan or on the plane?
Can I insert my SIM card in advance in Taiwan or on the plane?

The best practice is to replace your SIM card with ours after you arrive in the country. Installation instructions are also included with the product!

What should I do if my eSIM keeps showing as enabled after scanning?
If the scan in Taiwan shows "Enabling" or "Unable to Enable," this is normal ; it means the eSIM has been successfully installed and is loading. Do not delete the eSIM at this time!
👉1. Please wait patiently for approximately 15 to 45 minutes. Once the phone has finished reading, it will display "Unable to enable eSIM". This is normal because the phone has not yet acquired a local signal. 👉2. After the reading is complete, please turn off the eSIM number. Once you arrive at your destination, turn it on and switch to mobile data to start accessing the internet!
