For the first time in days, Iranians were able to make calls abroad from their mobiles on Tuesday, according to reporting by Associated Press. Texting services have not been restored, however, and nor has the internet.

Although Iranians were able to call abroad, they could not receive calls from outside the country, several people in the capital told Associated Press. The internet remained blocked, they said, though it is possible to access some government-approved websites.

Cloudfare - an internet infrastructure provider, and one of several companies and monitors tracking the status of internet traffic in Iran – said traffic volumes have remained “at a fraction of a percent of previous levels”. Its latest update as of 01:00 UTC (which is about three hours and 30 minutes ago), shows a continued widespread blackout. Iran has been under an internet shutdown since Thursday night.

Brief windows of connectivity were observed on Friday, but these did not last, according to Cloudfare.

Netblocks, an independent global internet monitor, also notes that while some phone calls from Iran are connecting, there is “no secure way to communicate” and the general public remain cut off from the outside world.
