    We are currently in Gozo, Malta and have been unable to connect to 3 since yesterday lunch time….we purchased a 12 gb bundle on Thursday and currently c9 gb left….all we get when we try to connect is cannot connect to server try again later. Seriously not impressed with the service. I do hope our month will be extended by this delay.
