outlook accounr because I am travelling and try to sign, hotmail is suspicous why I try to sign in not from location from where I usually sign in

You know guys, people travel. And while travelling they sign in from not the usual home ip. So outlook prompts me to enter the code that they say they will text me. Except there is no incoming text from outlook, alltho the tel number I have as security feature is correct, outlook simply wont send the text. So what  to  do? I chose 'call  me and give the code' option, but no phone call from Outlookl. Then as last resort I choose 'email the code to backup email address' which in my case is also  hotmail account. So bottom line is, alltho my login details and password are correct, Outlook wont let me sign in. I am travelling for 4 months. Am I correct assuming I wont be able to get to my hotmail inbox until I am back to my country, where I usually sign in. I find that to  be absolutely insane. The point of using email is that I can access my mail anywhere, but I am unable to. Can you guys at Outlook maybe try to  have security features that actually work, or just accept that people travel, and dont always sign in from same location. Maybe somebody from support reads this, and is able to help me, please! Sincerely, Veikko
