I am a bit overwhelmed by the information on this thread. I am going to be traveling to Nepal and likely to Zambia in the next couple of months. I am a Canadian looking for the best option (likely a global sim). I would like it to work on my transits via HK, Doha, Dubai, Istanbul etc. Any suggestions as to which is the best esim provider. I am open to buying one that lasts for a year/2 years etc. Also, I assume none of these providers give a tel no for making calls/SMS.

Thanks in advance,
