Been crap
Very crap lately
Like need time
Like 5 minutes to warm up then works
But when you stop using and use again , can't work
Works better when you are.like facing window
Oh
Have I mention it makes your phone very very hot when it huffs and puffs cos cannot connect to Internet
I have a feeling it relies on the set up by telcos cos some places like malls work fine. Guess the telcos' hub or set up is there
