What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: Transfering an eSIM from one phone to another is usually not possible. However some eSIMs can be transferred from one iPhone to another.

I purchased this ESIM for me and my wife for our Thailand trip.
Positives:
1. Purchased the sim on 20th Sept at 11:40 PM and received the QR code on 21st at 3 PM so good turnaround time
2. Seamless activation of SIM on my iPhone
Negatives:
1. Purchased one with both data and calls but only data was working after landing
2. Contacted customer care via email but got no response for 3 days
3. Got a response on 24th Sept with steps to activate on Dtac app but this sim number was not supported, hence emailed them again
4. Got this response on 26th Sept (2 days later):
Hello,
We apologize for the inconvenience caused to you. Thai govt has restricted the outgoing calls on all traveler SIM cards. Please visit nearest DTAC store and complete the KYC process to activate the outgoing calls.
Advice to mgmt: Improve customer care response time as well as any communication required beforhand by the customer

We are sorry for the negative customer service experience you have had. The Thai government has provided confusing guidance on process for KYC for outgoing voice calls. We apologise for the inconvenience once again and hope to be given the chance to serve you again. Thank you for taking the time to record your experiences.

I used Tsim during my trip to Thailand and was really impressed. The network coverage was excellent everywhere I went, and the data speeds were consistently fast. It made staying connected so easy throughout my trip. Highly recommend!
