Should I get an Amazon Echo?

I'm planning on buying an amazon echo dot and I wanted to know whether it is a good Idea for me and will I use it.

I have an iPhone 7 and a MacBook, I don't have any gadgets to turn my lights on and off and to change the heat in my room. I would use it for an alarm, to set reminders, to see what's on my calendar, to make a shopping list, to see the news, sports scores, movie times and the weather.
I watch Netflix a lot and order food from uber eats, just eat and deliveroo. I would also like it to ring people, read my notes, open things on my MacBook and play music.

I just wanted to know if it would do all these things and if it doesn't, what does it do and how well does it work with an iPhone and MacBook and what can I do with it?

I found this iphone?

So it seems new. I also said I can't set up the iphone right now. But i mostly need help with the screen fixing.

My voicemail does not work with my iPhone 7 Plus iOS 11(Wal-Mart Family Mobile)?

So my carrier is Wal-Mart Family Mobile, and I just recently bought a iPhone 7 Plus under T-Mobile with the iOS 11 update. Family mobile does not offer Visual Voicemail so I usually had to dial 1 to access my voicemail. But now since I got this new phone it says is not recognized, Please contact customer care…' I tried to access the Voicemail settings in the iPhone but for some reason it is not listed anywhere in my phone. I think it's because I don't have visual voicemail set up. Family mobile doesn't know how to fix the problem and I hope some one has the same issue as me and can direct me in the way to fix it

Why will my computers Wi-Fi NEVER work?

So around 2 months ago m computer all of a sudden began to never pick up Wi-Fi, i was using a USB wireless adapter at the time, and running Windows 7 Ultimate. It all of a sudden wouldn't install the device and whenever it did it wouldn't connect to my home Wi-Fi. My homes Wi-Fi speed isn't the greatest, however my iPhones 4G hotspot is 40MB down and 30UP and i had 'Limited Acess' (Yellow Cone) whenever connecting.

I upgraded to Windows 10 Pro (Legit) and have bought two new wireless adapters, and still getting the same problems.

'Limited Acess'
'Couldn't Connect To This Network'

Whenever i do finally connect, i can load up one webpage in around 10 seconds and then 'Limited Access' occurs again.

I have tried updating drivers, reinstalling and uninstalling everything, restore points, cmd prompt commands, not much is working.

I thought something may be missing within Windows itself but seeing as though i have upgraded i don't see how that may still be an issue (Although i didn't clean install)

Can someone please help me?
