TM Invalid MMI Code on 143#
Quick Fixes That Work
Seeing an invalid TM MMI code error can stop you cold. You dial *143# to check a balance, open a menu, or buy a promo, and your phone answers with “Connection problem or Invalid MMI Code” instead.
That error usually does not mean *143# is gone for good. Globe’s current help pages still show *143# in active prepaid flows, while GlobeOne now handles a lot of the same account tasks through the app. it’s crucial to ensure that your SIM card is registered. TM SIM registration is now mandatory under the Philippine SIM Registration Act.
What does the invalid MMI code mean
An MMI code is a short command your phone sends to the network or to the device itself. Commands like *143# and *#06# fall into the same general dialer-command bucket, which is why people often talk about them like USSD codes. When the phone fails to process the command, it can show “Invalid MMI Code” or “Connection Error.”
In plain English, your phone is trying to talk to the network, and something interrupts that exchange. The cause may be a weak signal, a SIM card issue, a network-setting problem, or a phone-side conflict.
For Touch Mobile users in the Philippines, the confusion grew because older forum posts suggested that *143# had been replaced completely by the GlobeOne app. Globe’s official help pages tell a more accurate story: the app is central now, but *143# still appears in current support flows.
- Re-enter the code carefully
- Restart the phone
- Toggle Airplane Mode
- Check your mobile signal
- Remove and reinsert the SIM card
- Set network mode to LTE/3G/2G (auto)
- If you use a Dual-SIM phone, test with one SIM enabled
Common reasons for TM invalid MMI code
Most TM invalid MMI code problems come from a short list of causes. That is actually good news, because it gives you a logical place to start.
The code was entered incorrectly
A missing #, an outdated code, or a copied string from an old blog can break the command. Lifewire lists incorrect or incompatible MMI codes as one of the most common reasons the error appears.
Your signal is weak or unstable
If the network is weak, the request may fail before the menu opens. Globe says network problems can come from congestion, indoor coverage issues, and low signal areas.
The SIM card is loose, dirty, old, or defective
A poorly seated SIM card can interrupt the connection between the phone and the network. Globe tells users to remove and reinsert the SIM during troubleshooting, and Lifewire also flags damaged or dirty SIM cards as a common cause of MMI errors.
The network mode is not set properly
Globe recommends setting the phone to LTE/3G/2G (Auto) when troubleshooting missing signal or connection issues. If your phone is stuck in a bad mode for your area, MMI requests can fail.
A dual-SIM conflict is getting in the way
Dual-SIM phones are useful, but they can also create routing conflicts. LifeWire lists SIM card conflict on dual-SIM Android phones as a known trigger for Invalid MMI Code errors.
Your SIM may be outdated
Globe notes that older SIMs or devices may no longer align well with newer network technologies. Globe also offers SIM CHECK through 8080 so users can confirm whether the SIM is LTE-ready.
Does 143# still work for Globe and TM?
Yes, it still works in the current Globe support flows. Globe’s prepaid help pages still direct users to dial *143# for loan status, and Globe’s mobile data help page still points users to *143# through MyAccount > Data Balance.
Globe also still references *143# in promo-related and international calling paths. For example, Globe’s prepaid promo pages and international promo help pages continue to show *143# as a registration or status route.
At the same time, Globe describes GlobeOne as the app for managing Postpaid, Prepaid, and TM accounts. That explains why many users now use the app first, even though the dial code still appears in official help content.
Why do many users think 143# no longer works
This confusion did not appear out of thin air. In one Reddit thread from the Philippines, a user said a new Globe prepaid SIM returned an invalid MMI code after dialing *143#, and one reply claimed everything had moved to GlobeOne.
That idea spread because it felt believable. Apps were becoming the default path for account management, promo registration, and support. Globe’s own app pages reinforce that shift by positioning GlobeOne as the main account hub.
Still, believable is not the same as accurate. Globe’s newer help pages continue to show *143# in active prepaid and service-related paths, so the better conclusion is that the code still works in many cases, but it can fail on certain phones, settings, or SIM setups.
Quick diagnosis table
Use this table to narrow the problem before you start trying everything.
What you see | Most likely cause | Best first step |
*143# fails right away | Incorrect code or dialer issue | Re-enter the code carefully |
Network or coverage problem | Move to a better area and retry | |
The app works, but *143# fails | Dialer or MMI handling issue | Use GlobeOne while troubleshooting |
The problem started after moving SIMs | Poor SIM contact | Remove and reinsert the SIM |
Two SIMs are active | Dual-SIM conflict | Disable one SIM and test again |
SIM fails across phones | Faulty or outdated SIM | Consider SIM replacement |
The table above lines up with Globe’s troubleshooting flow and Lifewire’s Android-level fixes. Both sources start with basic connection checks before moving to stronger steps.
Best order to try the fixes
Follow this order so you do not waste time.
- Re-enter *143#
- Restart the phone
- Toggle Airplane Mode
- Check the signal
- Reinsert the SIM card
- Set network mode to LTE/3G/2G (Auto)
- Disable one SIM on dual-SIM phones
- Use GlobeOne
- Run SIM CHECK through 8080
- Update Android
- Reset network settings
- Test the SIM in another phone
- Request SIM replacement if needed
That order matters because most TM invalid MMI code errors come from a weak connection between your phone, SIM, and the network. Start with simple fixes before you try anything drastic. Updating your APN for TM gives your device a fresh pathway to talk with the telecom towers.
How to fix the TM invalid MMI code on Android
The smartest way to troubleshoot is to move from easy fixes to stronger ones. Don’t start with a factory reset when a simple restart might do the job.
Re-enter 143# carefully
Type *143# manually. Check the symbols and make sure the final # is there. If you are trying any other USSD code, verify that it still appears in the current Globe help content.
Restart your phone
A restart can refresh the connection between the phone, the radio, and the mobile network. Globe’s own troubleshooting page starts with restarting the phone, and Lifewire lists the same fix near the top.
Turn Airplane Mode off and back on
This forces the phone to reconnect to the network. Globe specifically tells users to turn off Airplane Mode during troubleshooting, and Lifewire notes that toggling it can help clear MMI-related connection glitches.
Check your signal before retrying
If you are inside a low-coverage area, the request may never reach the network cleanly. Move near a window, step outdoors, or try again in a stronger coverage spot. Globe says weak signal and building interference can affect service quality.
Remove and reinsert the SIM card
Take out the SIM, wait a bit, then place it back correctly. Globe recommends removing and reinserting the SIM after 30 seconds, and Globe’s own troubleshooting blog adds that a badly seated SIM or dirty contacts can interfere with service.
Set network mode to LTE/3G/2G (auto)
This step matters more than many guides admit. Globe specifically says to set the network mode to LTE/3G/2G (Auto) when no signal or connection problems appear. That gives the phone a better chance to latch onto the right network path for your area.
Disable one SIM on a dual-SIM phone
If you use two SIMs, turn one off and test the TM or Globe SIM on its own. LifeWire lists dual-SIM conflict as a common cause of the Invalid MMI Code message, so this is a smart low-risk test.
Use the GlobeOne app
Sometimes the practical move is to bypass the dialer and get the task done. Globe says GlobeOne can manage TM, Prepaid, and Postpaid accounts, track usage, register promos, and surface help options.
Check if your SIM is LTE-ready
Text SIM CHECK to 8080. Globe says this check is free and can be done up to 5 times per day, and the reply confirms the type of SIM in your device.
Update Android and your key apps
Lifewire recommends updating Android because software bugs, app conflicts, and old system files can affect MMI processing. This will not fix every case, but it is a worthwhile step when basic fixes fail.
Reset network settings
If the problem keeps coming back, a network settings reset can clear deeper connection issues. Lifewire includes this as a stronger fix before more extreme options like a full device reset.
Should you try the comma trick?
Some Android guides suggest adding a comma to the code as a workaround. Lifewire includes that option and explains it as a way to override how the phone handles the command.
It is worth knowing about, but it should not be your first move. This is not an official Globe troubleshooting step, and it works more like a device-level hack than a reliable carrier fix.
A good rule of thumb is simple: try official Globe steps first, then use Android-specific fallback tricks later. That keeps you grounded in what is most likely to work.
GlobeOne app vs. 143#: Which should you use?
The best answer is not either-or. Many users will use both depending on the task.
Use *143# when you need a quick menu, and your line is processing dialer commands correctly. It still appears in official Globe help for loans, data-balance paths, international promo status, and some promo registration flows.
Use GlobeOne when you want broader account management, easier promo registration, usage tracking, or help options in one place. Globe describes GlobeOne as the app for managing TM, prepaid, and postpaid accounts, and the app’s troubleshooting pages also show built-in help flows for billing, account changes, connection concerns, and promo-related issues.
Here is the practical comparison:
Task | *143# | GlobeOne app |
Quick menu access | Yes | No dialer menu, but direct app options |
Data balance path | Yes | Yes |
Promo registration | Yes, in some flows | Yes |
Loan status | Yes | Yes |
Account help | Limited | Stronger support tools |
TM account management | Partial | Yes |
Globe’s own help pages support both paths, which is why the smartest article does not pretend one has replaced the other in every case. Discover how to Pasaload in TM using regular text messages to bypass the broken interactive prompt entirely.
Useful Globe and TM codes to know
Not every code list floating around online is still reliable. Older telecom code roundups age fast, so it is smarter to keep the list short and verified.
*143#
This remains the main code users look for first. Globe still references it in current help pages for loan status, data balance, promo paths, and some international calling promo flows.
*#06#
This code shows the device IMEI. Globe’s mobile unlocking help page tells users to dial *#06# to display the IMEI number.
SIM CHECK to 8080
This one is not an MMI code, but it is useful. Globe says texting SIM CHECK to 8080 confirms the type of SIM in your phone, and the request is free.
DATA BAL to 8080
Globe’s mobile data help page says users can check remaining data by texting DATA BAL to 8080, using the GlobeOne dashboard, or dialing *143# and selecting MyAccount > Data Balance.
When basic restarts fail you will need to contact TM customer service to check for network outages.
What to do if 143# still does not work
If you have tried the standard fixes and the code still fails, it is time to narrow the issue more aggressively. The goal now is to separate a phone problem from a SIM problem.
Test the SIM in another phone
Globe recommends this directly. If the SIM works in another handset, the problem likely sits with your phone. If it fails in both devices, the SIM or line is the stronger suspect.
Check whether other services work
Ask a few simple questions:
- Can you make calls?
- Can you receive texts?
- Does mobile data work?
- Does GlobeOne recognize your account?
- Is your SIM active and properly registered?
If multiple services are failing, then the issue is bigger than *143#. That usually points back to the SIM card, network connection, or account setup.
Request SIM replacement if needed
Globe says users can request a SIM replacement through the GlobeOne app or by visiting a Globe store. Globe also says newly issued replacement SIMs are activated within 24 hours when processed in-store.
Globe further says replacement options can cover a damaged SIM, a switch from a physical SIM to an eSIM, or an upgrade to a 5G-enabled SIM. The replacement SIM supports 3G, 4G LTE, and 5G in selected locations with compatible devices.
Use official Globe help channels
If you are still stuck, skip the rumor mill. Globe’s contact and help pages direct users toward self-service channels and support routes through GlobeOne and Globe’s official contact paths.
Mistakes to avoid
A lot of weak tech articles throw every possible fix at the reader. That creates noise instead of clarity.
Avoid these common mistakes:
- Don’t assume every old forum comment is current
- Don’t jump straight to a factory reset
- Don’t treat the comma trick like a guaranteed fix
- Don’t ignore the SIM card
- Don’t assume GlobeOne means *143# vanished overnight
The best troubleshooting is simple, methodical, and boring in the best way. Start with the obvious. Then move to the stronger fixes only if you need them.
Conclusion
A TM invalid MMI code error does not automatically mean *143# is dead. In most cases, the issue comes from the connection between your phone, SIM, and the network, not from some major carrier-side shutdown.
Start with the simple fixes first. Re-enter the code, restart the phone, check the signal, reinsert the SIM, switch the network mode, and use GlobeOne if you need a faster workaround. If the problem keeps returning, test the SIM in another phone or move to SIM replacement through Globe’s official channels.
Frequently Asked Questions
