The social media site made the decision to temporarily halt the feature allowing users to post via text message due to "vulnerabilities that need to be addressed".

The Twitter Support profile wrote: "We're temporarily turning off the ability to Tweet via SMS, or text message, to protect people's accounts.

"We're taking this step because of vulnerabilities that need to be addressed by mobile carriers and our reliance on having a linked phone number for two-factor authentication (we're working on improving this).

"We'll reactivate this in markets that depend on SMS for reliable communication soon while we work on our longer-term strategy for this feature."

Twitter stopped the service after its CEO Jack Dorsey's account was hacked last week.

Those responsible tweeted racist, sexist and anti-Semitic comments on his profile, including also posting bomb threats.
