Roam1 Mobiles is highly unprofessional and unethical when it comes to dealing with customer queries. I inquired about a sim card for Singapre which they said would be delivered well in time and being a pre paid thing, I would have to recharge it to get going! Having agreed to everything, not only did they delay the delivery of the sim card, literally making me beg for a product that they sell but to top it up, their recharge system ate my money with no credit! Burnt my fingers and never recommending this unethical service provider to anyone else in the future!
