What is an eSIM?

An eSIM is a digital SIM that lets you connect to a mobile network without inserting a physical SIM card. You install it directly on a compatible phone using the QR code or activation instructions provided after purchase.

Are BITESIM plans data-only?

Yes. Unless a product page clearly states otherwise, BITESIM plans provide mobile data only and do not include a phone number, voice calls, or SMS.

Will I receive a physical SIM card?

No. Your eSIM is delivered digitally after successful payment. Nothing will be shipped to your address.

How will I receive my eSIM?

Your eSIM details and installation instructions will be delivered digitally, usually by email or through the order confirmation page. Please make sure your email address is correct before completing your purchase.

Will this eSIM work on my phone?

Your phone must support eSIM and must not be locked to a specific mobile carrier. Compatibility can also vary by device model, software version, and country of purchase, so please check your device before ordering.

How do I know if my phone is carrier-unlocked?

Contact your current mobile carrier or check your phone settings. On iPhone, you can usually find this under Settings > General > About > Carrier Lock. The wording and location may vary on Android devices.

When should I install my eSIM?

We recommend installing your eSIM while you have a stable Wi-Fi connection, preferably before travelling. However, activation timing and validity start may vary by plan, so always follow the instructions included with your order.

How do I install my eSIM?

Open the QR code on another device and scan it with your phone. If you are viewing the email on the phone you want to install, press and hold the QR code, then select “Install eSIM” or “Add eSIM” when available.

Can I install the same eSIM more than once？

Many eSIM profiles can only be installed once. Do not delete the eSIM after installation unless customer support specifically asks you to do so.

Can I keep my regular SIM active？

Most dual-SIM phones allow you to keep your regular SIM active while using BITESIM for mobile data. Your home carrier may still charge for calls, SMS, or roaming, so review your primary SIM settings carefully.

When does my plan start?

The validity start depends on the plan. Some plans may start after installation, while others start when the eSIM first connects to a supported network. Check the product page and activation instructions for your specific plan.

Do I need to turn on data roaming?

Many travel eSIM plans require data roaming to be enabled for the BITESIM line. Follow the setup instructions included with your order and make sure mobile data is assigned to the correct eSIM.

Can I use personal hotspot or tethering?

Hotspot availability depends on the plan, destination network, and your device. If hotspot use is important to you, check the relevant product details before purchasing.

What happens when I use all my data?

Your mobile data connection may stop or become limited after the included allowance is used. Depending on the plan, you may need to purchase a new plan or an available top-up.

Why is my internet speed different in different locations?

Coverage and speed depend on local network conditions, your exact location, buildings, congestion, device settings, roaming arrangements, and the local operator. The same plan may perform differently across locations.

I have not received my eSIM email. What should I do?

Check your spam or junk folder and confirm that the email address used during checkout is correct. If the email is still missing, contact customer support with your order number and purchase email.

My eSIM is installed but cannot connect. What should I check?

Confirm that the BITESIM line is enabled, mobile data is assigned to it, and data roaming is turned on if required. Restart your phone and review the network or APN instructions included with your order.

Can I request a refund?

Refund eligibility depends on the delivery, installation, activation, and usage status of the eSIM. Activated or used eSIM products may not be refundable. Please review our Refund Policy and contact support before deleting the eSIM.

What information should I provide when contacting support?

Please provide your order number, purchase email, destination, phone model, screenshots of the issue, and any error messages. This will help us investigate the problem more quickly.
