Hello fellow Developers.
Under the following premise, what happens when you have 2-step validation enabled to access your work account in microsoft at the URL https://login.microsoftonline.com/, it tells you to put username and password, then how is it configured the option that sends SMS to the phone number sends it or if you prefer make a validation call (dial from anywhere in the world), the call or SMS message validation is made and you enter your account.
Now what happens if in Mexico specifically in Mexico City the numbers with the code 55 are finished and the code 56 is added to have 2 dialing codes and the new numbers are extended, we would say that the number 55-11-22- 33-44 is different than 56-11-22-33-44, why?, Because they are different because of the code, even if they refer to the following numbers that are the same and can be carried by different people (that's why they added the new code 56, Recycling numbers no longer used with code 55 did not work)
Now when dialing from SKYPE with the +52 1 55 xxxxxxxxx call, calls are made without problems to mobile numbers, when this changes to code 56 of the example mobile numbers; +52 1 56 xxxxxxxx indicates that:
The number you entered is not valid. Check it out and try again.
By contacting Skype help and after trying to reason them they indicated that it is not a Skype error that is a telephone number error, since it is not true, because how many applications today send an SMS or call to validate the authenticity (ebay, whatsapp, amazon, facebook, Google) all this through the mobile phone number.
Remember the premise, it is the number with code (56): 56-11-22-33-44 (example), so it can not be an error of the telephone line when trying to receive calls or sms since you are ebay, whatsapp, amazon, facebook, Google, etc. applications They send calls or SMS to the number with code 56 and Skype not in Mexico.
* He was informed that the mobile phone had a signal and internet access.
Tests were made with another number with code 56 giving the same message.
The 2 numbers with code 56 are from different Movistar and AT&T operators, they were available for testing.
Tests were carried out with a telephone without signal with key 55 of the operator AT&T and sent to voice mail, which is correct.
They indicated changing the code from 56 to 55 to the number: 56 11 22 33 44 (example) but they were made the observation that that number could answer the call another person, leaving the number 55 11 22 33 44 and in the dialing + 521 5511223344, as they were mentioned, gave a ringtone and the other person sent a mailbox, I never zoned the real number we had in sight.
