Network Settings Configuration

Network Mode Selection

• 5G/4G/3G/2G Auto (Recommended): Automatically switches between networks. Best for most users. Balances speed and battery life.
• 4G/3G/2G Auto: No 5G, better battery life. Good for areas with poor 5G. Stable connection.
• 3G/2G Only: Emergency use only. Very slow speeds. Maximum battery saving.

Frequently Asked Questions (FAQs)

Why does my mobile data stop working despite full signal bars?

This is the most common issue in India. Usually caused by: (1) Data balance exhausted, (2) Network congestion, (3) APN configuration error, (4) Temporary network glitch. First check data balance by dialing operator codes, then toggle Airplane Mode for 30 seconds. If still not working, reset network settings.

How do I check if my area has 5G coverage?

Download operator apps: Jio True 5G, Airtel Thanks, or Vi app. These apps have real-time coverage maps showing where 5G is available in your city. Major cities have 90%+ coverage, while smaller cities have limited coverage expected to expand by late 2026.

Should I use 5G or 4G for better battery life?

4G provides better battery life. 5G consumes 20-30% more battery due to more powerful modems and faster data processing. To save battery, switch to 4G when you don't need 5G speeds, use 5G Auto mode on iPhone, close background apps, and avoid heavy tasks on 5G.

How do I activate 5G on Jio?

Jio 5G is usually automatic for eligible users. To check: SMS "GET5G" to 199. Download Jio True 5G app to verify coverage and activation status. If not activated after 48 hours, call Jio customer care at 198. Ensure your SIM is in the primary slot and 5G is enabled in phone settings.

Is 5G available in smaller cities?

5G deployment in smaller cities is ongoing. As of May 2026, tier-3 cities have limited 5G coverage (30% Jio, 25% Airtel). Coverage is expected to expand to 40-50% by late 2026. Use operator apps to check real-time coverage in your specific area. If 5G isn't available yet, expect rollout within 6-12 months.

Why does my phone overheat on 5G?

5G modems generate more heat than 4G modems, especially during heavy use. Some warmth is normal. To reduce overheating: remove phone case, avoid direct sunlight, limit heavy tasks (gaming, 4K streaming) on 5G, take breaks to let phone cool down, and switch to 4G if phone gets too hot.

Should I keep 5G always on?

If battery life is a priority, use 5G/4G auto mode instead of 5G only. iPhone users should select "5G Auto" instead of "5G On" for better battery life. If you need maximum speeds and don't care about battery, keep 5G on. Switch to 4G when battery is low to extend usage time.

How long does 5G activation take?

After sending "GET5G" SMS to your operator, activation typically takes 24-48 hours. Some users get activated within a few hours, others may take up to 3-4 days depending on location and network congestion. If not activated after 5 days, contact customer care.
