Before purchasing a mobile signal booster, it’s essential to know which frequency bands your mobile carrier uses in your region. Using the wrong frequency booster will result in no signal improvement.
Android:
Dial *#0011# or *#*#4636#*#* to enter Service/Test Mode. Look for “Band” or “Frequency.”
iPhone:
Dial *3001#12345#* → Press call → Tap “Serving Cell Info” → Find “Freq Band Indicator.”
