Frequently Asked Questions

When can signal boosters be illegal?

Signal boosters can be considered illegal when they amplify mobile signals without control, causing harmful interference. Unregulated boosters may overpower nearby networks, disrupt mobile towers, or interfere with signals used by essential or government services. This is why many countries enforce strict rules on booster safety and performance. With OmniAmplifier, you do not need to worry. Our boosters are engineered with Smart Auto Gain Control (AGC), a safety technology that automatically adjusts amplification levels to prevent overload. They also include uplink and downlink shutdown features, which turn off transmission if the signal becomes too strong. This ensures:

  • No interference with nearby networks
  • Compliance with telecommunications standards
  • Safe operation in homes, offices, boats, cars, and more

How many users can connect at the same time?

OmniAmplifier boosters support multiple simultaneous users. Whether it is family, guests, or an entire office floor, all can enjoy improved signal at the same time without performance loss.

Can I install the booster myself?

Yes. All our systems are plug-and-play with simple instructions. Most customers complete installation in under 20 minutes without any technical skills.

Do boosters work for all carriers?

Yes. Our multi-band systems are designed to support all major carriers, and they will automatically boost whichever network your phone is using, including 3G, 4G, and 5G low or high band.

Will a booster improve 5G?

Yes, if your provider uses 5G on one of the supported frequency bands. Our boosters support:

  • Low-band 5G at 700 MHz
  • High-band 5G at 3500 MHz

This means you will benefit from boosted coverage wherever your carrier transmits 5G on these bands.

Can I return my signal booster if I’m not satisfied?

Yes. You may return your signal booster within 30 days of purchase, provided it is in good, undamaged condition and includes all original accessories, cables, and components.

How long does delivery take?

  • Delivery times typically range from 5–10 business days, depending on your location.
  • Estimated total delivery time is approximately 6-12 business days, including order processing.
