WELLCOME TO KEEPGO
Keepgo | International roaming SIM card and mobile WiFi hotspot
Travel the world free of roaming fees with prepaid global mobile WiFi for Europe, Asia, North & South America. Refill your data as you go. Ships free worldwide.
Slightly different proposition. While with KnowRoaming you are paying per day, with KeepGo you pay upfront for 1GB of data. Initial outlay is US$70 (US$59.50 if you use a referral code, pm me for details if you are interested, note I get 300MB free data) for a sim. They also are selling a wifi hotspot as well. Data is valid for a year.
On the face of it, it does sound like quite a lot, but this would work well if you are supplementing with free hotel wifi and probably best used for a weekend trip. Asia coverage is better than KnowRoaming and covers places like China, but at the same time Asia coverage isn't totally complete.
Yes, yes, there are cheaper options out there, such as local sim cards and even prepaid sim cards offered by the likes of China Mobile / Three and csl, but these all have some sort of restrictions. Like I said I think this service could work well for people going on weekend trips who just need a bit of data roaming while out and about to supplement their hotel wifi. Its not going to be for everyone, but I can see a purpose.
EDIT: Just want to add that shipping to HK isn't cheap (US$2, which may be a bit of a problem. They offer free shipping to North America and Europe, but not to Asia. I've had it sent to family in Europe who are coming to HK in the new few weeks.
