What speed should I get on Zong?
Many users report strong 4G speeds in cities, but as with every operator, performance depends on the local tower and time of day.
Your package speed is the maximum. A fair test is several runs at your usual locations and times. If you consistently get far less, collect screenshots of at least three results on different days before complaining.
Why is Zong slow? Common problems and fixes
| Symptom | Likely cause and fix |
