if you put Hatzalah’s number at the top of your contacts list, you should be careful that no one accidentally dials Hatzalah by mistake. I know on my phone, the first contact gets called once in a while. But luckily, its only a company.
Also, if you put Hatzalah as a speed dial, make sure no one presses it by mistake.
This is very important especially if you give your cell phone to kids to play with…
