How To Check Moche SIM Number: The Definitive Guide To Identifying And Managing Your Line

To quickly check your Moche SIM number, dial *#123# on your mobile device and press the call button to receive an instant on-screen notification containing your balance and phone number. Alternatively, navigating to the "Phone" or "About Phone" section in your device settings or logging into the My MEO digital portal provides comprehensive subscriber identity details. These methods utilize standard GSM Unstructured Supplementary Service Data (USSD) protocols to retrieve MSISDN information directly from the Altice Portugal Home Location Register (HLR).

Pre-Verification Requirements for Moche Subscribers

Before attempting to retrieve your Moche (Altice Portugal) subscriber number, it is essential to ensure that your hardware and network connection meet specific technical benchmarks. Moche operates as a specialized youth-oriented sub-brand under the MEO umbrella, utilizing the same cellular infrastructure and USSD gateways. Consequently, the environment in which you perform these checks must be stable to prevent MMI (Man-Machine Interface) code errors or timeout failures.

Foundational Checklist for SIM Identification:

• Network Hardware: A GSM/UMTS/LTE compatible mobile handset with the Moche SIM card correctly seated in the primary SIM slot.
• Signal Strength: A minimum of two bars of cellular reception on the MEO/Moche network. USSD codes require an active connection to the signaling channel (SDCCH), even if you have zero monetary credit.
• SIM Status: The SIM card must not be "Permanently Blocked" or expired. If a PUK code is required, you must resolve the security lock before the network can broadcast identity data.
• Estimated Duration: 30 to 60 seconds for USSD retrieval; 3 to 5 minutes for digital portal navigation.
• Required Information: Your physical SIM card (for ICCID inspection) or access to the device’s keypad.

Comprehensive Step-by-Step Methods to Identify Your Moche Number

Retrieving a forgotten or unknown mobile number involves several technical pathways, ranging from low-level network signaling to high-level application interface interactions. Depending on whether you have an active balance or internet access, you can choose the method that best suits your current technical environment.

Step 1: Executing the USSD Protocol Command

The most direct and authoritative way to check a Moche number is through the Unstructured Supplementary Service Data (USSD) gateway. This method bypasses the need for data plans or third-party applications by communicating directly with the network's signaling plane.

1. Open the "Phone" or "Dialer" application on your smartphone.
2. Input the shortcode *#123# using the numeric keypad.
3. Press the "Call" or "Send" button.
4. Wait for the network to process the request. Within seconds, a pop-up menu or "flash" message will appear on your screen.
5. Observe the text displayed. For Moche subscribers, this message typically shows your current balance, the name of your tariff (e.g., Moche 1GB, 5GB, or 10GB), and your mobile number (MSISDN).

Pro-Tip: If the *#123# code returns an "Error performing request" or "Unknown Application" message, restart your device to re-establish a fresh handshake with the local cell tower and try again.

Step 2: Utilizing Device-Level Identity Settings

Modern mobile operating systems (iOS and Android) are designed to read the MSISDN (Mobile Station International Subscriber Directory Number) directly from the SIM card's metadata, provided the carrier has written the number to the SIM's internal memory.

For Android Users:

1. Navigate to the "Settings" menu.
2. Scroll down and select "About Phone" or "Phone Information."
3. Tap on "Status" or "SIM Status."
4. Look for the field labeled "My Phone Number." If the network has provisioned the SIM correctly, your Moche number will be displayed here.

For iOS (iPhone) Users:

1. Open the "Settings" app.
2. Scroll down to the "Phone" section.
3. Locate the "My Number" field at the top of the screen.
4. Alternatively, open the "Contacts" app and tap on "My Card" at the very top of the list.

Warning: Occasionally, ported numbers or newly activated SIM cards may show "Unknown" in these settings. This occurs when the MSISDN is not hardcoded into the SIM's EF-MSISDN (Elementary File) record. In such cases, use the USSD method described in Step 1.

Step 3: Accessing the My MEO Digital Ecosystem

As Moche is a brand powered by MEO (Altice), your subscriber data is managed within the My MEO customer portal. This is the most reliable method for users who need to check multiple lines or managed accounts.

1. Visit the official My MEO website or open the My MEO application on your device.
2. Log in using your registered email and password. If you have previously linked your Moche line to an Altice ID, the dashboard will automatically load.
3. Navigate to the "Os Meus Produtos" (My Products) or "Perfil" (Profile) section.
4. The interface will display all active mobile lines associated with your NIF (Tax Identification Number), including the specific Moche number you are searching for.
5. This portal also provides the ICCID (Integrated Circuit Card Identifier), which is the 19-digit serial number unique to your physical SIM card.

Step 4: External Verification via SMS or Outbound Call

If the USSD and software methods fail due to technical glitches, the most practical "real-world" solution is to force the network to display your Caller ID on another device.

1. Ensure you have at least a minimum balance or an active "Free SMS/Calls" period included in your Moche plan.
2. Call a friend or family member who is standing near you.
3. The number appearing on their screen is your Moche MSISDN.
4. If you do not have credit, you can send a "Collect Call" (Pagaqui) or a "Call Me" request if the service is currently supported by your specific Moche sub-tariff.

Step 5: Physical Inspection of the SIM Architecture

In scenarios where the SIM card is not currently inside a phone or the phone is non-functional, you can identify the line using the physical characteristics of the SIM.

1. Eject the SIM tray using a SIM tool or a paperclip.
2. Remove the SIM card and examine the gold-plated side and the reverse plastic side.
3. Locate the 19 or 20-digit number printed on the plastic. This is the ICCID.
4. While the ICCID is not your phone number, you can provide this number to MEO/Moche customer support (16200) or check it against your original starter pack (Moche Welcome Kit) to identify the associated phone number.

Moche Service Codes and Technical Specifications

The following table outlines the essential technical codes and parameters used within the Moche/Altice network for line management and identification.

Common SIM Identification Failures & Field Fixes

Even with the correct codes, technical hurdles can prevent you from seeing your Moche number. Below are the most common failure scenarios encountered by subscribers and the expert-level remedies to resolve them.

• Problem: "MMI Code Started" followed by "Connection Problem or Invalid MMI Code"

  
  
  
  • Root Cause: This usually occurs due to a temporary desynchronization between the handset and the Base Station Controller (BSC) or when the phone is forced onto a 4G/5G band that does not support USSD over IMS without specific carrier configurations.
  • Actionable Fix: Switch your phone's "Preferred Network Type" to 2G or 3G in the mobile network settings, then re-run the *#123# code. Once the number is retrieved, you can switch back to 4G/5G.

• Problem: The Settings Menu Displays "Unknown Number"

  
  
  
  • Root Cause: The MSISDN record on the SIM card is blank. This is common with "unactivated" SIM cards or cards that have been ported between carriers.
  • Actionable Fix: Use an Android device to manually write the number to the SIM (if the OS permits) or simply rely on the *#123# USSD method, which pulls data from the network database rather than the local SIM storage.

• Problem: No Signal or "Emergency Calls Only"

  
  
  
  • Root Cause: The SIM card may be deactivated due to a lack of top-ups (recharges) for more than 90–180 days, or the SIM card's physical contact points are dirty/damaged.
  • Actionable Fix: Clean the SIM's gold contacts with a microfiber cloth and re-insert. If the "No Signal" persists, visit a MEO store with your ID to check if the number has been recycled or if you require a SIM swap (2ª via).

Frequently Asked Questions

Can I check my Moche number if I have no balance?

Yes, checking your number via the *#123# USSD code is a free service provided by Altice Portugal. It does not require an active balance, though your SIM card must be active and within its validity period to communicate with the network.

Does the Moche SIM number change when I switch plans?

No, your phone number (MSISDN) remains the same even if you upgrade or downgrade your Moche plan (e.g., moving from a 5GB plan to a 10GB plan). The number is tied to the SIM card's ICCID and your subscriber account, not the specific tariff.

How do I find my Moche number if I am abroad (Roaming)?

While roaming, you can still use the *#123# code in most countries, although some foreign networks may not support USSD commands. In such cases, the most reliable method is to check your number via the My MEO app using a Wi-Fi connection.

Is the Moche number the same as the serial number on the back of the SIM?

No, the number on the back of the SIM is the ICCID (Integrated Circuit Card Identifier), which is 19 digits long. Your Moche phone number is a 9-digit MSISDN (usually starting with 92, 96, or 91 if ported). The ICCID is used by technicians to link your physical chip to your mobile number in the billing system.

Why is my Moche number not showing in WhatsApp settings?

WhatsApp displays the number you used during the initial verification process. If you have changed SIM cards but not updated your WhatsApp account, it will show your old number. To see the number currently tied to the SIM, use the *#123# dialer code.
