Just now, the 139 email address of Mobile sent me a text message saying that I would receive a free blood glucose meter. Is it really free of charge? Isn’t this a lie?

It is very possible to get a blood glucose meter for free. Because when using a blood glucose meter to measure blood sugar, you need to use blood glucose test strips. A test strip is required for each test, and only dedicated blood glucose test strips are used for each blood glucose meter. Therefore, the blood glucose meter is provided for free, and if you want to buy blood glucose test strips, the cost can be recovered quickly. There is no free lunch in the world.
