To to be honest? speed is better with this Vectone then with smarty in the whole East London.
That makes no sense - don't bet on what? You've just said that all mobile customer services are dreadful, which is not exactly news to me - I've yet to time a company with consistent, good cs, so I go mainly on cost and coverage. Smarty is cheap and the coverage from their parent network works well where I live.
Don't bet on it!! You've not encountered their online only customer service. I had one to try to see what the signal was like, terrible in my area, tried and failed several time with customer service. But to be fair, most mobile customer services are dreadful (none worse than Virgin mobile).
Only 3g, who cares. My '4g' connection with 3 is 3mbps or less. However my wife's 3g connection with Virgin/ee (she hasn't updated her SIM card) is often 20/30mbps! If it's 3g on EE, it'll still be quicker than 3 in my area.
Rubbish. Use the SIM in any device you wish. Use as much of the data allowance for tethering as you wish (if you have the patience to try). This company is so pathetic it doesn't understand its mandatory obligations or hasn't bother update its t&c, either of which indicates its ineptitude. Anybody who likes to play with idiotic companies can have a field day here, and let's be honest: a lot of people may have some time to kill at the moment, so maybe start with Vectone, and it's very simple with this blunt piece of Euro-sourced legislation: Net Neutrality Regulation (EU) 2015/2120 Article 3 (3): "Providers of internet access services shall treat all traffic equally, when providing internet access services, without discrimination, restriction or interference, and irrespective of the sender and receiver, the content accessed or distributed, the applications or services used or provided, or the terminal equipment used." http://www.legislation.gov.uk/eur/2015/2120/article/3/adopted Maybe start by informing OFCOM https://ofcomforms.secure.force.com/formentry/SitesFormCCTMonitoring
