Ask servicing agent to check like colaboy said OR a better and more reliable way is to call customer service and ask them to explain to you.

You mean claim limit?
Unlimited lifetime limit = YES
Unlimited annual limit = Never heard of yet, anyone can update?

Dear morning 06 and activexxx,

There is none in the market that are providing such coverage of unlimited annual and lifetime limit. However, Great Eastern do have a medical card which the premium can be RM175/month for a 20years old, non smoker, male, occupation class 1 covering annual limit of RM990,000 and unlimited lifetime limit.

We should actually look into annual limit instead of lifetime limit as we are purchasing insurance to hedge for unexpected large risk.
Insurance is one of the financial planning as well as purchasing property, purchasing unit trust etc. All of the financial tool are having different purpose and limitation be it the risk, liquidity and penalty for early withdrawal.
