iPhone 12 hotspot disconnecting from laptop

I do not have the internet at home, I do however have unlimited data on my mobile phone contract, so I don't need a router, landline etc.

I connect to the internet via the phone hotspot but it randomly disconnects, which is very frustrating to say the least.

Due to the pandemic I am working from home, so I can be sitting working on a document that I do not need a connection for, but have my work email connected. I then go to check on emails and find that ones I have been waiting on might have been sent to me hours ago, but as the hotspot has decided to disconnect then I've had no notification of them arriving - I do not have my work email on my phone - I guard my private time very well. This has caused a lot of problems in my working life, with missing deadlines for replying and the work having to be put over to the coming month. I have tried Apple support, but they are less than useless and give the "we deal with billing" answer no matter who I contact - this is an absolutely woeful issue and Apples lack of any attempt to fix it is shocking.

I never had this issue with my Google Pixel and wish I had never moved to Apple, you can be sure of one thing though, I'll never buy another Apple product and I can't wait till this contract is over so I can go back to the Android system.

Pixel definitely was a better phone and Android a better system - Apple seem to have a silent Cr in front of their name!
