Knowing the claims process before buying travel insurance is a good idea. People think the claims process is intentionally complicated to avoid paying compensation, but that's not true. Once you understand the process, you realize it's straightforward indeed.
Keep a copy of your travel insurance policy with you. If you buy the policy online through BuyAnyInsurance.ae, a soft copy is sent to you in your email. A soft copy on your phone is just as good as a hard copy if you don't want to carry too many papers on your travels.
