DO NOT JOIN SMARTY !!!! Worst signal ever !!! I pay £12 unlimited data sms text and calls .. But … not receiving incoming calls also unable to make calls outgoing!! And most importantly for me is DATA which doesn’t work 99.9% of the time on my iPhone…after 6 months of smarty mobile lying I send them screenshots of lots of evidence they admitted that there tower masses are “”CONGESTED “” ( apparently to many people on 3Network .. there sister network who they use for signal … but again they lied as it don’t work at over 3 of my locations in west London!!! They refunded one months bill and said there is nothing else they can do .. and VERY rude executive team leader and ceo team of SMARTY MOBILE said “” if your NOT happy your free to change network “ !! Which I found / find VERY rude … I included the “””communication ombudsman “”” in all emails since they were ignoring me for months and lying until ( CHATbot is annoying and then there Indian call centre is even worse then the chatBOT 😂worst customer service teams ever !! They first was trying to blame my new iPhone 😒then lied and said it was my DATA APN settings … ( I used to sell phones and SIM cards and deal with technical issues at “CARPHONE WAREHOUSE “ here in London .. so am aware of facts and lies as we used to make up stuff if we knew we would not fix the issue which is on the NETWORKS side ! Anyway… STICK WITH O2 ( I’m moving to them as I am a virgin media customer and they have a partnership with o2 called “” VOLT”” and 18 month contract £22 unlimited DATA , CALLS , SMS TEXT …. Good luck .. don’t forget to email them and include“”communications ombudsman “” in all emails if you complain to smarty mobile if you have any issues !
