The minimum speed required to make a successful GSM call can vary depending on factors such as network coverage and signal quality. However, in general, you can make a successful GSM call while traveling at speeds up to around 120-130 km/h (75-80 mph) on highways, as long as there is strong network coverage.

Is there any way to travel by light speed?
With current technology, it is not possible to even come anywhere close to the speed of light. For example, traveling at 1/10 the speed of light is still science fiction. On the other hand, for anything that does NOT travel at the speed of light, it is impossible to actually attain the speed of light. In theory you might get close. There are some particles, such as photons and the hypothetical gravitons, which ONLY travel at the speed of light.
