Before I started my journey, I bought and activated my eSim line on Globaltel.rs and it is quite easy. As a prepaid plan with 600 RSD, 10 GB, 50 min/sms and 50 RSD credits are loaded as tariffs. Valid for 1 month, you can purchase appropriate credits or packages in additional packages. There is also a chance to earn GB with the referral program.

On the purchase page, it asks you for the address and number of Serbia, I filled it with the information I found on the internet. 1 minute after purchase, eSim profile and number were sent to my mailbox by e-mail.
