Hi PP, thank you for sharing your experience. We have checked your order details; you purchased the physical eSIM card and card reader bundle, not the EIOTCLUB USB dongle.
the reader itself cannot provide network connectivity to a computer in the way a USB network adapter (such as a portable Wi-Fi dongle) does.
Card Reader: Its function is similar to a standard SD card reader. An SD card reader is plugged into a computer to allow it to 'read or write' photos and files, not to turn the computer into a camera. Similarly, this eSIM card reader is plugged into a computer so that the management software can read, write, activate, or manage the physical eSIM chip (eSIM profile) inserted into it. The 12 Mbps transfer rate refers to the speed at which card configuration data is read or written, not the broadband speed used for internet access. It lacks a modem and an RF antenna; to provide network connectivity directly when plugged into a computer, a device requires a built-in modem to receive 4G/5G wireless signals from a carrier and convert them into data the computer can use. This reader is very compact and does not contain the communication hardware necessary for internet access.
How it actually works:
Writing the configuration: You insert a specialized, rewritable physical eSIM medium card into the reader.
Connecting to the computer: You plug the reader into the computer and use the accompanying software to write a downloaded eSIM profile (such as a third-party eSIM profile) onto the card via the 12 Mbps data channel.
Inserting into a device for internet access: Once writing is complete, you remove the card from the reader and insert it into a router, smartphone, or MiFi device that supports physical SIM cards. Only then can those devices use their own communication antennas and modems to actually connect to the internet.
Therefore, even if the eSIM profile is activated, simply plugging the card reader into your computer won't allow for direct data transfer to enable internet access, nor will inserting it into your TP-Link TL-MR3020 allow you to connect to the network.
To achieve what you want, you need the EIOTCLUB USB dongle; this dongle comes with a built-in SIM card, so you can plug it directly into your computer to use it immediately.
Thank you for your support of EIOTCLUB
