Disclaimer. I am not very tech savy. I rent office space which doesnt get cell reception. I can make my wifi calls on my cell phone but it certainly is not ideal and at time it become problematic. The person I rent the space from will likely not give me access to their modem/router for me to plug in one of those OBI phones. I do have internet from them, i just dont think they will allow me to plug anything into their router/modem. Is there any internet phone like OBI that doesnt need a direct plug in and will work directly off wifi? Not sure what to do about this problem I am having
