* You share with a friend so you always have to be together
* I use up all the data quickly.
* It's a hassle to go through the rental process and return it
If you always buy a SIM after arriving in the country
* I have to set up my SIM in a local language I'm not familiar with
* It's a hassle to replace the SIM each time.
