The services were suspended in the two cities since 10am.
Interior Minister Rehman Malik ordered the suspension of cellphone services as a measure to prevent terrorist activities.
"The mobile phone services have been restored now in Karachi and Quetta," Ali Faysal, a senior official of the Pakistan Telecommunications Authority (PTA) told AFP.
Javed Odho, a senior police official in Karachi earlier told AFP that "police had intelligence reports about (the) possibility of a very big terrorist attack in Karachi and it was because of this reason that the mobile phone service was shut down".
"It is a preventative measure taken to effectively counter (the) terrorism threat," he said.
Odho said the decision was taken after top police officials held lengthy meetings. "Pros outweighed cons. This was the only effective way to block conversation of terrorists, who use mobile phones to plan attacks," he said.
Authorities feared that mobile phones could be used to coordinate attacks or trigger a remote-controlled bomb.
Odho said thousands of policemen have been deployed all over Karachi to perform duties alongside paramilitary rangers.
Security measures in Quetta
The government has imposed a ban on pillion riding and display of weapons in the Quetta city.
The ban will remain in effect for two months.
Balochistan Home Secretary Akbar Durrani on Friday warned of a serious security threat especially during the first 10 days of Muharram.
"At least eight provincial districts have been declared sensitive and the army troops will be on call to deal with any untoward situation," Durrani said.
Correction: An earlier version of the story erroneously reported that the Sindh High Court ordered restoration of cellular services in Karachi. The error has been fixed.

Can anyone suspend him for a change and see the difference it makes!
Good Decision From Rehman Malik
Despite Rehman Maliks attempts at "saving" the nation from terrorists if the terrorists manage to out do his spectacular thinking abilities, how will hospitals respond to emergencies in case of any untoward occurrence?
The concept of Target Killings needs to be redirected towards these politicians rather than the layman being targeted. We'd be a much happier and successful nation with this lot gone for good.
@Atif: wow Curfew means another holiday
@Atif: Curfew is far better than that
@Salman Rajan: Hahaha nice one and certainly you can click some snaps for facebook & twitter that how you look during this shutdown ;-)
@Speaker: Sir, don't you think that suspending cellular service is the most stupid decision by government.... just think about those who are in hospital or in any other emergency.... what would they do if they need to contact someone? should they go to ask for help in person? Government has harmed Pakistan very much...
There should be a complete curfew in karachi for peace, could be an idea in future by Dr.Malik
@not impressed:
Thank you :)
The courts are now dealing out of its boundaries. This not their matter of concern. They are not improving the quality of justice.
our cj wants to compete with cjp , who takes more so mo to !
Play games on you cell phone till then :)
Judge should be a judge not an administrator
Clash of institutions are quite visible.
Ministry of Interior vs Chief Justice of Sindh High Court.
Who will be responsible when innocent people will die in target killings during the month of Moharram?
@Human: i hear they will be restored at 7pm
only 2-3 telephones will be used by terrorits and why to affect the whole population of Quetta and Karachi. Very few people using motor cycles in Quetta
@Human: 5 pm .. You can play games on your cell phone till then.
Yup, Im getting the Homing pigeons ready. Theres going to be a huge demand for them.
@Human ...Till the time our honourable interior minister thinks karachi is safe .i.e. No longer facing any threats. How sick?
This is your incompetent PPP/MQM led government's solution to terrorism.
Good no mobile snatching in Karachi today.
We still need a consensus if we are a failed state, however it is unanimous that we are a failed government.
time to abandon the green passport... there is nothing left in this country.. This is moving in the direction of madness. Internet, media freedom, mobile, pillion, freedom of speech, freedom of religion, everything is curtailed.
WTG CHamp! You just saved the entire nation
Lol
Can somebody take 'The (true) Idiots Guide For Security' from Dr. Rehman Malik?
Stone age my friend or may be just stoned!
Cellphone services are already suspended in Karachi too any idea till what time ?
