0/10 would not recommend them to my worst enemy

1 star is very generous, -5 stars would be more apt. I started using Supersonic F-LTE in November 2020, it worked for 2 weeks and never again. After technical issues It took 3 weeks to deliver a replacement sim which didn't work and to top it off they still billed me for all those months despite not using a single 1kb of data that month due to their bad network. The worst network ever. 0/10 would not recommend them
