Options for setting up on-call paging for INC tickets

[Ben124]

Hello,

Currently we have paging setup for INCs in a mostly OOB way.  Every so often a SMS message doesn't hit the person on-call for several hours or even a few days.  However, that ONLY happens for people on Verizon using vtext.com messaging.  The question I have is, what options do we have besides the OOB options for paging.  Right now, (generally speaking) if a P1 or P2 INC hits and there is an on-call schedule that matches, then we have the system send an email, a push, and a text at about 5 minutes between.  Of course, the users can change their alerting preferences to only get texts, only get pushes, get all three types each time, etc...but one thing remains the same...sometimes the people who are on Verizon don't get the SMS messages timely (other times they do).

So I'm wondering, is there another, better way to do this (ideally without spending more money somewhere)?  Is there some application/plugin we can get that will help send the alerts in a more reliable way?  Verizon Support said they no longer support vtext.com, so there isn't much they can do...but it looks like in ServiceNow we've got to send SMS to them in that way.

Thank you for any help!

I don't know if it matters....but we have some users in our instance on Verizon cell phones setup with the following for text messages:

@vzvmg.biz

instead of 

@vtext.com

Might be worth testing

Thank you!  I can't find any documentation from Verizon around @vzvmg.biz.  Do you happen to know why you use this?  I can call Verizon to find out more, just hoping you might know/remember why that was picked to switch over to.

Additionally, for anyone else reading this does anyone have any other solutions than using vtext or @vzvmg.biz?  Thanks!
