All Telcos Except Jazz Fail in PTA’s Quality Test

Telenor, Zong and Ufone have missed most of the key performance indicators (KPIs) set in their license and applicable regulations, revealed an independent quality of service survey carried out by Pakistan Telecommunication Authority (PTA).

PTA has released the findings of the independent survey carried out in the 3rd & 4th Quarters 2019 to check the Quality of Service (QoS) of Cellular Mobile Operators (CMOs) from September to December 2019 in twelve (12) different cities of Balochistan, Khyber Pakhtunkhwa, Punjab, Sindh and Azad Jammu Kashmir.

The names of these cities are:

  • Abbottabad,
  • Charsadda,
  • Gujranwala,
  • Murree,
  • Muzaffarabad,
  • Sargodha,
  • Sibbi,
  • Sukkur,
  • Thatta,
  • Swabi,
  • TandoAllahYar
  • Taxila.

The performance of data services of CMOs has been checked by measuring User Data Throughput and Signal Strength (i.e. Received Signal Code Power (RSCP) for 3G and Reference Signal Receive Power (RSRP) for 4G.


PTA Suspends 5G Trials for Zong and Jazz

Signal Power

The signal strength KPI defines Received Signal Code Power (RSCP) for 3G and Reference Signal Receive Power (RSRP) for 4G and denotes the power measured by a receiver on a particular physical communication channel. It is used as an indication of signal strength, as a handover criterion, in downlink power control, and to calculate path loss”.

RSCP of 3G Network of all CMOs was observed to be greater than -100 dBm with 90 percent confidence. RSRP of 4G Network falls short of the minimum threshold (-100 dBm with 90 percent confidence) both in urban and rural areas. Telenor and Zong failed to achieve the desired threshold in Rural Areas.

Grade of Service

Grade of Service is the probability that the end customer cannot access the mobile services when requested if it is offered by the display of the network indicator on the mobile phone. In simple words, Grade of Service is Network Blocking”. Telenor failed to meet this threshold value (Threshold: ≤ 2%) in both rural and urban areas. Ufone was unable to achieve the desired threshold in urban areas.



Service Access

Service Accessibility is the probability that the user can access the desired service. A given network’s accessibility is a precondition for this phase. Telenor failed to achieve the criteria (Threshold: > 98%) of Service Accessibility in both urban and rural areas.

Call Connection Time

Call Connection Time is the time between sending of complete call initiation information by the caller and in return receipt of call setup notification. In simple words, it is the time between dialing a number and hearing a ring-back tone. Zong failed to achieve the benchmark (Threshold: ≤ 6.5 sec) of Call Connection Time of 6.5 seconds.

Call Completion Ratio

Call Completion Ratio is the probability that a service, once obtained, will continue to be provided under given conditions for a given time duration or until deliberately terminated by either caller (A-party) or receiver (B-party). In simple words, this KPI provides information about Call Drops. Telenor failed to meet the threshold value of 98 percent.

Inter System Handover

Inter System Handover is the measurement of successful Handover in 3G/2G for Circuit Switched Voice. Ufone failed to meet the threshold value of 98% in urban areas. Zong failed to meet the threshold value of 98% in rural areas.

SMS Reliability

The performance of SMS services of CMOs has been checked by measuring SMS Success Rate and End-to-End SMS Delivery Time Key Performance Indicators (KPIs).

SMS Success Rate is the probability that the short message is delivered successfully, end-to-end when requested and display of the relevant information on the mobile phone. It provides information about the successful delivery of SMS. SMS Success Rate of Telenor and Ufone were observed below 99 percent in urban areas.


End-to-End SMS Delivery Time is the time between sending a short message to a short message center and receiving the very same short message at the intended mobile phone (receiver). It provides average time taken for delivery of short message from sender to recipient. All CMOs are meeting the threshold for End-to-End SMS Delivery Time of 12 Seconds.

Internet Rate

User Data Throughput KPI defines user data rate (Internet speed) to be provided by CMOs to mobile users across the coverage areas. User data “throughput” of 3G services needs to be higher than the threshold value of 256Kbps while User data “throughput” of 4G services should be higher than the threshold value of 2Mpbs. All networks passed the test.


Voice Quality

The performance of voice services of CMOs has been checked by measuring Network Down Time/Network Accessibility, Grade of Service, Service Accessibility, Call Connection Time, Call Completion Ratio, End-to-End Speech Quality and Session Abnormal Release Rate Key Performance Indicators (KPIs).

“The probability that mobile services are available to an end customer display of the network indicator on the mobile equipment”. The CMOs have met the threshold value of Network Accessibility.


End-to-End Speech Quality is the degree of speech quality that a listener perceives at the terminal/mobile with a talker at the other end. In simple words, it provides information about the clarity of voice. Mean Opinion Score (MOS) of CMOs was found to be above the threshold value of 3.

  • Kudos to Mobilink (Jazz).

    they earned the place with teams dedication. Here i just want to mention that the way they treated their employees in current virus scenario is beyond words. Taking care each employee and even concerning on the well being of their family is step ahead.

    Few on ground facts: Daily meal allowance for lower field staff, Sanitizers, gloves etc for families and same for retailers

    Company who take good care of their employees always WIN

  • So, Telenor failed almost in all departments. The company lacks focus and is more concerned about 5G these days. Used to be one of the best networks but now the story is totally different.

  • This is careless reporting and the post title along with results must be reviewed before submission
    It is mentioned in 4G signal Strength “Telenor and Zong failed to achieve the desired threshold in Rural Areas.” whereas in graph JAZZ also failed to achieve the threshold. JAZZ even failed in overall 4G coverage whereas Zong and Telenor met the threshold.

    For Zong, most of the KPI are met but in the first line, it is mentioned that “Telenor, Zong, and Ufone have missed most of the key performance indicators (KPIs)”

    The link to the official publication of PTA report should also be shared as I am unable to get this report from PTA site.

  • Thanks ProPk for highlighting most essential aspect of Ratings by the PTA. The regulatory authority rates one of the highest in the ITU index of regulators globally in the emerging markets. There is a need to rate the mobile devices, handsets, routers on PK networks. As we’re rapidly progressing towards the era of 5G in Pakistan dominated by Huawei PRC. The Financial Times, London rated 5G Networks by Nancy Pelosi warns Europe over Huawei 5G dangers. An important consideration by the respective regulatory authority.

  • jazz is the most pathetic organization i have seen. their customer care is extremely pathetic.

  • LoL

    Jazz the most stupid network in Pakistan

    and the PTA Fuck off with ur testing Cities Come in Punjab and Sindh then tell us who is fucking stupid network is there

  • In which world do these stats are gathered? Jazz in my experience and I mean in a lot of cities is absolutely pathetic in terms of coverage and service quality.

  • I think it’s fake survey, most likely I should call it paid survey, I was ufone user since last 13 years, I switched network to jazz, I appreciate jazz call packages but not data plans, and the call connection service which jazz provides too much worse then others, too much wait for call connection and if connected the service quality is much more then worse ?
