Hi Danielle,
Thank you for your reply.
The hotspot (ZTE F50) is set to connect to 5G but when I look at the available bands it connect only to a 4G band (N3) limiting the speed to 10-20Mbps. If I fix the hotspot to use only the 5G bands SIM does not connect to Sunrise network although the hotspot is capable of. This is the problem.
I changed the sim to We connect wifi where the down to download speed is 2Gb but the issue stayed. Only 4G network band and low speed.
Regulars, Peter
