Robi Internet Settings: APN, 4G, 5G Setup for Android and iPhone

If you just inserted a Robi SIM into your phone and mobile data is not working, the fix is almost always a simple APN configuration. Robi uses a single APN value across all its networks — 2G, 3G, 4G LTE, and 5G — which makes the setup straightforward once you know exactly where to look on your device. In this guide I will walk you through every method: automatic USSD codes, SMS-based configuration, and full manual APN setup for Android and iPhone.

Robi APN Settings at a Glance

Before diving into step-by-step instructions, here is the complete APN configuration table you will need for manual setup. These values are current for 2026 and work on all Robi network tiers including 4.5G and VoLTE-enabled SIMs.

The APN value internet is all lowercase and must be entered exactly as shown. Any capitalisation or extra characters will prevent the connection from working.

Method 1: Automatic Setup via USSD Code

This is the fastest method and works on virtually every Android phone. Open your dialer and call the following code directly from your Robi SIM:

Dial: *1233*1#

Within a few seconds you will receive an SMS containing all internet and MMS configuration settings. Open the message, tap the settings bundle, and save it as the default profile. Your mobile data should activate immediately after saving.

An older alternative code that still works on some accounts is *121*7*6*1#. If the first code does not deliver the SMS, try this one. Both point to Robi’s over-the-air configuration delivery system.

Method 2: Automatic Setup via SMS

If you prefer SMS-based configuration, send a message to 8738 with your phone model name in the body. For example, type Internet Samsung Galaxy A55 and send it to 8738. Robi’s system will reply with a preconfigured settings bundle matched to your device model.

If you are unsure of your exact model name, you can type the first eight digits of your IMEI number after the word Internet. You can find your IMEI by dialling *#06# from your dialer.

Method 3: Manual APN Setup on Android

Manual setup is necessary when automatic methods fail or when you have reset your network settings. The steps below apply to most Android phones including Samsung, Xiaomi, Realme, Oppo, Vivo, and Motorola. The exact menu labels may differ slightly depending on your Android version and manufacturer skin.

Step 1: Open Settings

Go to your phone’s Settings app. Look for Connections or Mobile Networks — on some phones it sits under More Settings or Network and Internet.

Step 2: Find Access Point Names

Tap Mobile Networks, then select Access Point Names. If you have a dual-SIM phone, make sure you select the SIM slot where your Robi SIM is inserted.

Step 3: Add a New APN

Tap the + icon or the Add button in the top right corner to create a new APN profile.

Step 4: Enter the APN Values

Fill in the fields using the table above. The only field that must have a value is APN: internet. Leave all proxy, username, password, and MMS fields blank unless you specifically need MMS support.

Step 5: Save and Select

Tap the three-dot menu and select Save. Then tap on your newly created profile to select it as the active APN. Toggle mobile data off and on once to apply the new settings.

If mobile data still does not work after saving, go back to Mobile Networks and set your Preferred Network Type to LTE/4G or 5G if your SIM supports it. Robi offers 4.5G coverage across most of Dhaka and major urban areas in Bangladesh.

Method 4: Robi Internet Settings on iPhone

iPhone handles APN configuration differently from Android. On iOS 15 and later, Apple automatically fetches carrier settings when you insert a new SIM, so you may not need to configure anything manually. However, if your Robi data is not working on iPhone, follow these steps.

Automatic Carrier Update

Go to Settings > General > About. If a carrier settings update is available, iOS will prompt you to install it. Tap Update and your APN will be configured automatically.

Manual APN on iPhone

Apple removed the manual APN field from the standard Settings menu on newer iOS versions. To configure it manually you need to either use a carrier configuration profile or access the hidden cellular data network menu:

1. Go to Settings > Cellular > Cellular Data Network (this option may not appear on all iOS versions).
2. Under the Cellular Data section, enter internet in the APN field.
3. Leave Username and Password blank.
4. Scroll down to the LTE Setup (Optional) section and enter internet in the APN field there as well.
5. Go back and toggle Cellular Data off and on.

If the Cellular Data Network menu does not appear, restart your iPhone with the Robi SIM inserted. iOS should auto-detect the carrier and apply the correct APN. If it still does not work, contact Robi customer care at 123 from your Robi number.

Robi MMS Settings

MMS (multimedia messaging) requires a separate APN configuration from regular internet. Most users in Bangladesh no longer use MMS actively, but if you need it for sending photo messages or for certain app notifications, here are the MMS APN values for Robi:

Create this as a separate APN profile alongside your internet APN. Do not merge the two — keeping them separate ensures your regular mobile data is not affected by the MMS proxy settings.

Robi Internet Settings for Mobile Hotspot

Once your APN is correctly configured, your Robi SIM will also work as a mobile hotspot without any additional setup. Go to Settings > Mobile Hotspot and Tethering on Android and toggle the hotspot on. Your internet APN automatically handles hotspot traffic.

One issue some users face is the Android hotspot turning off automatically after a few minutes of inactivity. This is a battery optimisation setting in Android, not a Robi network issue. You can fix it by disabling hotspot timeout in your hotspot settings or adjusting battery optimisation for the hotspot feature.

Robi 4G and 5G Network Settings

The APN value internet works identically across Robi’s 2G, 3G, 4G LTE, 4.5G, and 5G networks. You do not need a different APN for higher speed tiers. What determines your network speed is your SIM capability and your phone’s network band support.

To ensure you are connecting to 4G or 5G rather than falling back to 3G, go to Settings > Mobile Networks > Preferred Network Type and select 5G/LTE/3G/2G (Auto) or the highest available option on your device. Robi’s 5G rollout is ongoing in Bangladesh, currently covering select areas of Dhaka, Chittagong, and Sylhet.

If you are travelling internationally and need mobile data abroad, check whether your plan includes roaming. Robi offers international data roaming in over 150 countries. Make sure Data Roaming is toggled on in your mobile network settings before departure. For frequent travellers, comparing international phone plans for travellers may help you decide whether a local SIM or a global plan makes better financial sense.

Robi My App: The Easiest Setup Method

Robi’s official app — My Robi — is available on both the Google Play Store and Apple App Store. When you log in with your Robi number, the app can automatically push the correct APN settings to your device. It also manages your data packages, balance, and account settings from a single interface.

For users who are not comfortable with manual APN configuration, downloading My Robi and letting it auto-configure is the simplest route. The app also offers 2 GB bonus data on first login for new registrations.

Troubleshooting Robi Internet Not Working

If you followed the setup steps and internet is still not working on your Robi SIM, work through this checklist before calling support:

1. Check Your SIM Slot

On dual-SIM phones, confirm the Robi SIM is in the correct slot and that mobile data is assigned to that SIM. Go to Settings > SIM Card Manager (or Mobile Data in your connections menu) and set Robi as the preferred SIM for mobile data.

2. Restart Your Phone

A full restart refreshes your device’s connection to the Robi tower and clears any cached network state. This fixes the majority of temporary mobile data issues.

3. Verify Your Data Package

Dial *8444*88# to check your remaining data balance. If your package has expired or your balance is zero, internet will not work regardless of your APN settings.

4. Check Network Coverage

Confirm you are in a Robi coverage area. In remote or rural parts of Bangladesh, 4G coverage may be limited. Try switching your preferred network type to 3G/2G temporarily to test basic connectivity.

5. Re-enter APN Settings

Delete your existing Robi APN profile and create a fresh one using the values in the table above. Sometimes a corrupted or incomplete APN entry from a previous setup attempt causes persistent failures.

6. Reset Network Settings

As a last resort, go to Settings > General Management > Reset > Reset Network Settings. This clears all saved Wi-Fi passwords, Bluetooth pairings, and APN profiles and lets you start fresh. If you encounter a broader unidentified network error on any device after resetting, reconfigure the APN from scratch using the values above.

7. Use Android Wi-Fi Assistant

If you frequently switch between mobile data and public Wi-Fi and notice connectivity drops, Android’s built-in Wi-Fi assistant for public networks can help maintain a stable and secure connection while you move between hotspots.

8. Contact Robi Support

If none of the above steps resolve the issue, call 123 from your Robi number (free of charge) or visit a Robi Service Centre. Bring your phone and NID for faster assistance. Robi support can remotely push configuration settings directly to your SIM if the issue is on the network side.
