I love the e sims now available on line to use travelling. Easysim was particularly easy and I felt comfortable with a brand I recognised. I chose cheep option of 1gb on country I was in first but that ran out abot 2,/3 through tbe week . So I liked the option where I could but some that covered many countries so I was good for the end of shilanka trip and then few days in doha. Mind you . I ran out again. So I don't think that 1gb is enough. I am not a big user it was more for maps away from hotels and online hotel searches but 1gb seamed not to last more than 3 or 4 days. . I did use there customer service on email. They were very helpful. Overall I would recommend.
