I used TSIM for 7 day South East Asia pack, they did provide me eSim on time, SIM worked in Vietnam, Cambodia & Thailand without any problem.- Worked wonderfully at Montenegro. Link for download of sim for ios does not work. eSim download has to be done manually. The process requires a 4 digit pin. All these details are not mentioned anywhere. However, Tsim customer service is responsive and solved eSim download issue. I would strongly recommend Tsim.
Best esim option for short visits. I did a short business trip and this has been the most economical option for esim. Great work!!
