Hi, Thanks a lot for your continuious support. I have a Call and Data sim card that I am currently using with a Huawei B525 4G modem. I want to replace the Huawei with the Spitz the problem is that the Spitz does not have a RJ11/RJ12 port to link it to a home phone. I would rather make use of the 2 hours (free call allowance i get every month). Is there a way I can do that with the functionalities provided within Spitz or any modem provided by GL.INET ? many thanks ---

We don’t have a device that supports RJ11/RJ12. ---

Thanks, That’s a shame because i think a lot of users are in the same scenario I am in. We love the VPN/WireGuard functionality but we have a dataplan with calling Credit (a home phone type thing). Is there anyway I could use something to still be able to use the free calling allowance that comes with my Sim plan whilst using one of your 4G routers ? ---

If the Spitz doesn’t have the RJ11/RJ12 port you need, you might want to consider looking into alternative modem options provided by GL.INET. They might offer a solution that works for your setup and helps you take full advantage of those two hours of free calls every month. For more insights into how you can optimize your call setup and perhaps discover some new possibilities, you could check out this article [https://www.mightycall.com/blog/virtual-call-center/](https://www.mightycall.com/blog/virtual-call-center/).
