I got 3 calls from this number aswell. It says its not in service. But... its not the normal message i hear when I call other numbers that are not in service. I wonder if its on their end that they have a machine that picks up and does that. Could be scammers?

I too received a call from this number (416) 210-3998) on the 6th... My friend was in Barrie at the time and she used a calling card to talk to me that night, it wasn't till the next day I looked at the caller ID and thought that it was weird the call came from a 416# instead of a 705#. I haven't talked to her since to find out why a Toronto# came up instead of a Barrie#. I wonder if calling card companies cycle their phone numbers no matter where you are in the country?

also, when I call back the number and/or 4870 it doesnt work..

I got two calls in two days from (416) 210-3998.  I don't answer the call and let it go to voice.Woman left a msg saying she was looking for Tisha.  Her name was Hope and she left a number 1-(514) 865-7995 (in Quebec).  Her msg goes something like this:  Hi Tisha, it's Hope.  I have the stuff that you wanted for that lady sitting here.  Please call me back at (514) 865-7995 so that you could pick it up for her... (or something like it)...  Smells funny since she wasn't specific about what she had for Tisha.  Always referred to it as stuff or thing...

If it is just a calling card, explain this:-The voicemail it left me (automated voice) : "Your callback number is 4870"and then a text! (From 1-4870)"Please call 4870"
