5G comes in different variants of 5G depending on the frequency range:
• Low band (700–900 MHz) → long range, good indoors, but not that fast.
• Mid band → balance between speed and coverage (most common).
• High band (mmWave, 24–40 GHz) → extremely high speed, but short range.
These frequencies are not supported in all countries.
On TMUS, low band is all the way to 600 MHz for B71
