Hello,
I live in Slovakia and I am using hologram Nova as well as hologram SIM card to send classic circuit-switched SMS to my smartphone via GSM. Problem is, I can receive SMS perfectly fine on other carriers (tried O2, Telecom), by I have problem receiving SMS using Orange SIM card. I contacted Orange and they told me that nothing is being blocked and that technicians confirmed the messages are not flowing through their network. I tried other Orange SIM card and got the same result, I even tried sending SMS via cloud, but to no avail. Is there something else I could try to do?
Thanks
