The Problem

Your iPhone 15 Pro Max can't connect to 5G networks or keeps dropping to LTE/4G, preventing you from experiencing fast download speeds and responsive connectivity.

Common symptoms include:

  • 5G icon never appears even in 5G coverage areas
  • Phone stuck on LTE/4G despite 5G availability
  • Constantly switching between 5G and LTE
  • Slow data speeds despite showing 5G connection
  • 5G option grayed out or missing in cellular settings
  • Other 5G phones work fine in the same location

Our Solution

Our expert technicians will diagnose whether your 5G connectivity issue is caused by antenna damage, modem problems, or SIM compatibility, then perform the necessary repairs to restore full 5G functionality.

Why choose professionals:

  1. 83% DIY failure rate because 5G mmWave antennas require precise titanium frame alignment—incorrect installation causes permanent signal loss requiring $800+ logic board replacement when baseband processor fails from improper RF grounding
  2. Professional spectrum analyzer equipment and cellular testing tools measure 5G signal strength across sub-6GHz and mmWave bands, identifying antenna failures, modem malfunctions, and carrier compatibility issues invisible to consumer field test mode
  3. Common mistakes include damaging delicate 5G antenna arrays during titanium frame removal (causes permanent 5G loss, voids AppleCare+ coverage), failing to properly seat antenna connectors (reduces signal by 70%), and misdiagnosing carrier provisioning issues when modem requires micro-soldering repair costing $700+
  4. Our genuine 5G antennas maintain proper mmWave beam forming and carrier aggregation across all bands, while aftermarket antennas show 50% reduced speeds, frequent network disconnections, and iOS warnings about non-certified components affecting cellular performance
  5. We calibrate 5G modem for optimal band selection and power efficiency, test antenna performance across all carrier frequencies, and verify eSIM provisioning with major carriers—procedures requiring expensive specialized diagnostic equipment and carrier partnerships
  6. Same-day 5G diagnostics available—DIY attempts risk permanent antenna damage, titanium frame RF shield degradation, and missing underlying baseband failures that prevent connection to cellular networks entirely

When we all depend so heavily on our iPhones for so many reasons, when something is wrong, we have to get it fixed before we lose all of our information inside it, it can be stressful and caused lots of anxiety! I read and write reviews all over the country because I am a truck driver and when I found this review about GIZMO DEPOT,INC , and all of the other great reviews, that made my decision to come here and I’m so happy I did! THE OWNER AND OPERATOR’S NAME IS NA!! Yes NA, and she is so wonderful with such a beautiful smile and a great personality to go with it! She she is so reassuring and trustworthy, when you drop your phone off, and might have to have a little extra work done in 24 hours, you have complete reassurance that when you get it back everything including many important emails are still going to be accessible! Na assured me and made me know without a doubt that my two week HAWAII HONEYMOON vacation, and all my emails would be exactly where I left them! So , of course they were! When we drop our phones and the glass in the back is cracked, really badly, and she has to completely take that off, clean the entire phone by taking everything out, also inserting a new battery as requested and screensaver, to me the challenge of that type of job is indescribable and I’m so glad I found Na to do it!! I absolutely highly recommend everything that she does to fix all of your devices! Her expertise and knowledge of doing this here at this location for over 14 years is proof, of her wonderful service! Thanks so much again NA !! I will be telling everybody I know, if they ever need service, to come to see you first! I appreciate you! YOU ARE THE BEST!

Na is the best! I needed my xbox series x cleaned and she explained everything thoroughly and insisted on testing before and after the cleaning. great prices and even greater results in a short time! will definitely come again :)

The lady running this is excellent! Unfortunately with this review, there isn't more than 5 starts but should be at least 10 stars!!!! Very helpful, knowledgeable and gets to the bottom or real issues quickly and is reasonable cost for diagnostic services. Identifies real issues where phone carrier store people generally do not find real equipment issues, especially on older phones!!!!

Frequently Asked Questions

Why won't my iPhone 15 Pro Max connect to 5G?

5G connectivity issues can be caused by damaged 5G antennas (often from drops), faulty cellular modem, incorrect carrier settings, or SIM card incompatibility. We'll diagnose the exact cause and determine if it's a hardware issue requiring repair or a configuration problem we can fix.

Is 5G connectivity important enough to repair?

Absolutely! 5G offers dramatically faster download speeds, lower latency for gaming and video calls, and better performance in crowded areas. If you're paying for 5G service but stuck on LTE, you're not getting what you're paying for and missing out on the full iPhone 15 Pro Max experience.

Can carrier settings or SIM card issues cause 5G problems?

Yes, sometimes. We'll verify carrier settings and test with different SIM cards during diagnostics. However, if multiple SIMs and carriers don't work, it's a hardware issue requiring antenna or modem repair. We eliminate all software possibilities first.

Will 5G antenna repair affect regular cellular service?

No, your phone will still work on LTE/4G during and after repair. The 5G-specific antennas are separate from the main cellular antennas. We repair only the 5G components, ensuring both 5G and LTE connectivity work perfectly after service.
