A waste of time when I'm already stressed about preparing for travel - I'm not sure how the package can come with a missing SIM

I used the Keepgo SIM in my android phone for 5 months in Europe and it worked very well.

Overall, I would recommend this SIM for ease of use

a T-Mobile data SIM and the Keepgo SIM.The AT&T SIM worked very well, was completely automatic and had 4G speeds, but was also by far the most expensive.

The sim worked splendidly without any issues.
