I've also faced similar issue recently by JIO.
"
Acer Connect Enduro M3 5G" was working fine with 5G network. (although i'm always getting shitty speed - will share the ss).
They didn't blocked my CPE but they converted my 5G Network Access to 4G by saying that It is not available in INDIA currently and we can't switch your plan to 5G-Unlimited one.
Luckily, I've a 5G Phone access atm. So, I just inserted my SIM into 5G Phone and it was also not able to access 5G Network due to Block done by JIO.
After inserting my SIM into 5G Phone, I just called Customer Care and told them that I've 5G Phone but i'm not receiving 5G Internet. They said that "your SIM is not registered under 5G Something and will process with it". The customer care told me that my 5G Package has been activated and told me to restart my Device after 5 minutes. I did it and able to Receive 5G Network on my phone.
After this, I've inserted my SIM back into the CPE and started to Receive 5G Network on it.
So, They can unblock and allow you to use 5G Network. It just take 1 button from them to activate 5G Internet at your device but they started to give excuses if you use any CPE/Dongle/
Router which can access 5G Internet by saying lame excuses.
Better follow the above steps and you'll be able to access the internet easily.
