CMLink is a telecommunications company that offers global data SIMs, with a mobile presence in Italy, Japan, Thailand, the United Kingdom and Singapore. The “CM” in CMLink is an abbreviation for “China Mobile”, which helps explain why CMLink SIM-only plans have data allowances that are shareable across Singapore, Hong Kong and China.
CMLink in Singapore offers a handful of no-contract SIM-only plans and a few 12-month contract plans. All of CMLink’s mobile plans use the Singtel network. The list below shows the popular CMLink SIM-only plans that we track in our comparison engine.
