Answers for smoother journeys.

01 What is eSIM?General

An eSIM is a digital SIM embedded in your device. It connects to mobile networks without a physical SIM card and can be installed directly on a compatible phone or tablet.

02 How do I check if my phone is compatible with eSIM?General

Check your device settings for an option to add or manage an eSIM. You can also dial *#06# — if an EID number appears, that is a good indication that your device supports eSIM. Confirm the exact model in our compatible device list.

03 Is my phone carrier-unlocked?General

Your phone must be carrier-unlocked to use a travel eSIM. On iPhone, open Settings > General > About and check Carrier Lock. No SIM restrictions means the iPhone is unlocked. For other devices, contact the seller or carrier to confirm.

04 Can I use my physical SIM and eSIM at the same time?General

Yes. Most compatible phones support dual SIM mode, so you can keep your physical SIM for calls and messages while using the travel eSIM for mobile data.

05 Can I keep my original phone number?General

Yes. Use the travel eSIM for data and keep your original SIM active for calls and SMS, subject to your home carrier settings and roaming policy.

06 How do I receive my eSIM after purchase?Install

After payment, you will receive an email with your QR code, SM-DP+ server address and activation code. You can also view the eSIM details in your order history.

07 Can I install the eSIM before departure?Install

Yes. Install it while connected to stable Wi-Fi, then keep the eSIM turned off until you are ready to use it. Most plans start when the eSIM connects to a supported network, but always check the activation policy on the product page.

08 When should I install my travel eSIM?Install

Install it a few hours before departure or upon arrival. Keep the eSIM disabled and data roaming off until you are ready to connect, especially during a layover.

09 How do I install an eSIM with a QR code?Install

Connect to stable Wi-Fi, open your phone settings, choose Add eSIM or Add mobile plan, scan the QR code from your abesteSIM email, wait for the profile to download, and label the plan so you can identify it while travelling.

10 Can I enter the eSIM activation details manually?Install

Yes. In your phone settings choose Add eSIM or Add SIM, select the manual entry option, then enter the SM-DP+ address and activation code from your purchase email.

11 Can I get eSIMs for multiple countries or regions?Install

Yes. We offer single-country plans, regional plans such as Europe or Asia-Pacific, and global plans for wider coverage.

12 How do I activate my travel eSIM?Using

Turn on the newly added eSIM, enable data roaming for that eSIM, set it as the default mobile data line, and wait for the signal to appear. Manual network selection may be needed in some destinations.

13 How is my eSIM validity calculated?Using

Most plans begin when the eSIM first connects to a supported network and starts using data. Some plans use a fixed start date or activate on installation. Check the specific product description before purchase.

14 Can I top up my eSIM?Using

abesteSIM currently does not support topping up an installed eSIM. You may need to purchase a new data plan when your existing allowance ends.

15 Can I receive calls or SMS on a travel eSIM?Using

Most travel eSIMs are data-only, unless voice or SMS is clearly listed in the product description. You can keep your original SIM for calls and messages when supported by your home carrier.

16 Can I share data with other devices?Using

Yes. You can use your phone hotspot to share the travel eSIM data connection with friends, family or another device, subject to the plan and network settings.

17 Can I transfer my abesteSIM to another device?Using

Once installed, an eSIM is normally bonded to the device and cannot be transferred. Avoid deleting the profile unless you no longer need it. Contact support if you need help with a replacement.

18 How do I check my eSIM data usage?Using

Use the abesteSIM Usage Checker when available, check your device's cellular data usage screen, or use carrier notifications and USSD codes listed in the product details.

19 How do I set up APN on my phone?Using

APN settings are usually automatic. If needed, iPhone users can open Settings > Cellular > Cellular Data Network. Android users can open Network & Internet > Mobile Network > Access Point Names and enter the APN details from the purchase email.

20 How do I check the EID of my phone?Using

On iPhone, open Settings > General > About and scroll to EID. On Android, open About Phone > Status or SIM Status. You can also dial *#06# and check whether an EID appears with the IMEI.

21 Why will my eSIM not connect to the network?Troubleshooting

Confirm that you are in the supported destination, your phone is unlocked and compatible, the correct eSIM is enabled, data roaming is on, and a supported network is selected. If needed, turn off automatic network selection and choose a carrier manually, then restart the phone.

22 How do I fix the This code is no longer valid error?Troubleshooting

The QR code may already have been installed. Check your SIM settings for a new eSIM profile, use stable Wi-Fi, scan from the phone's Add eSIM settings instead of the camera app, restart the phone, or use the manual SM-DP+ and activation details.

23 What do I do if I delete or lose my eSIM QR code?Troubleshooting

Contact support@abestesim.com or our online chat. Include your order details and we can help locate or resend the installation information when eligible.

24 Why is my network speed slower than expected?Troubleshooting

Speed can be affected by location, signal strength, device compatibility, network congestion, radio bands and the selected carrier. Try manually switching to another supported network and restart your phone.

25 Why does unlimited data slow down?Troubleshooting

Some unlimited plans apply a Fair Usage Policy after high-speed usage reaches a threshold. Other plans have a stated speed cap such as 5Mbps, 10Mbps or 20Mbps. Check the product description for the exact plan terms.

26 What if my eSIM is activated but there is no internet?Troubleshooting

Make sure you are inside the supported coverage area, data roaming is enabled, the correct eSIM is selected for mobile data, and a supported carrier is connected. Try manually switching networks if the connection is still unavailable.

27 What if my phone is stuck on Activating?Troubleshooting

If you are not yet at the destination, activation may wait because the supported network is not available. Turn off the eSIM after the attempt and enable it when you arrive. If you are already in the destination, check roaming, signal and manual network selection, then restart the phone.
