It boosts signals for E-Plus, Aldi Talk, Blau, Ortel, and more. If you use any of these networks, this booster can help improve your signal! 4. Q: How do I install the mobile signal booster? A: Installing the mobile signal booster is not too complicated! First, you set up the outdoor antenna outside where you get some signal.
