I hv rented wifi pocket to England for 10 days but it doesn't work well. The battery is running out very quickly and charged very slowly. The connection to internet is weak and often disconnected. The pocket itself is so dim and I cannot see the battery level. I charged overnight and found in an hr , it said battery low. With power bank, it charged slowly and running out so quickly. I felt so upset and tired with this. Yesterday it disconnected for whole morning and afternoon, then a few hrs later the data reached limits.
