Ufone has activated 4G Plus, Long-Term Evolution Advanced, and Carrier Aggregation across Karachi, with users across the city confirming improved signal strength, more stable data connections, and noticeably better coverage following the ongoing integration of the Ufone and Telenor network infrastructure.
The upgrade is a direct outcome of a two-phase network evolution that began on May 11, when Ufone shut down its older 3G services and repurposed the freed bandwidth to reinforce its 4G infrastructure. The second phase of that process has now produced visible results, with devices catching stable 4G Plus signals across multiple areas of Karachi. Users have reported that Ufone is actively merging signals with former Telenor cell sites as part of the integration, which is filling coverage gaps that previously left parts of the city with inconsistent or weak connectivity. Those who previously experienced spotty connections in certain areas are now reporting stable 4G Plus speeds, reflecting the practical benefit of combining two separately licensed network footprints under a unified infrastructure.
One technical quirk has been noted for users whose devices do not yet support Voice over Long-Term Evolution. On such handsets, active phone calls cause the data connection to temporarily drop back to 2G, and the network identifier on the screen briefly switches to a numeric string before returning to the Ufone name once the call ends. This behaviour is a known limitation of non-VoLTE devices on 4G networks and is expected to affect a declining share of the user base as handset compatibility improves over time. Users currently experiencing this issue may wish to verify whether their device supports VoLTE and whether the feature can be enabled through a software update or network settings adjustment.
Beyond raw speed, Ufone’s current network posture is drawing positive feedback for a different reason: consistency. Users note that while networks such as Jazz and Zong can deliver faster peak speeds, they are more prone to congestion during rush hours and occasional complete outages during extended power cuts, particularly in Khyber Pakhtunkhwa. Ufone’s network, by contrast, is being described as more dependable during these periods, with connectivity holding up in situations where competing networks go dark. For a significant portion of subscribers, that reliability is proving more valuable than headline speed figures, and the Karachi rollout is serving as an early indicator of what the broader Ufone-Telenor integration could deliver for users in other cities as the process continues.
