No VOIP / text app please!

I’m sorry guys but I am not comfortable booking clients using VOIP / app numbers. For my own safety I’m only comfortable booking with a SIM card based phone. Prepaid SIM card phones are fine of course! I understand you guys use text apps for your privacy, but I’m sorry after a couple years of mischievous games played mostly from text apps, I refuse to accommodate the use of text apps or voip. I have many reasons why I don’t like text apps but my safety is my main concern above all. If you’ve sent a message & I haven’t answered it yet please feel free to give me a set time frame limit. You text me first always!
