Before you even think about activating your GLOBE SIM on a Huawei phone, there are a few non-negotiable things you need to have ready to avoid delays. Let’s break this down simply. First, your physical GLOBE SIM card – make sure it’s not damaged, has no bent pins, and is the correct size for your Huawei device. For example, if you have a Huawei P50 Pro, it uses a nano-SIM, so if your old SIM is a micro-SIM, you’ll need a SIM cutter or a new one from a GLOBE store. Next, your Huawei phone must be powered on and have at least 50% battery life – this prevents sudden shutdowns mid-activation which can mess up the process. Also, ensure you’re in an area with at least 2G or 3G signal; activation usually works on basic networks, not just 4G or 5G. A quick story: Last month, my cousin Maria from Manila tried activating her new GLOBE SIM on her Huawei Nova 9, but she was in a basement with no signal. She waited an hour and got an error, only to realize she had to go upstairs where there was a signal. Another thing: If this is a new SIM you got from GLOBE, it might have a default PIN (usually 1234) – don’t forget that, as you’ll need it if your phone asks for it during activation. Also, make sure your Huawei device is not locked to another network. Wait, how do you check that? You can insert a non-GLOBE SIM (like Smart) and see if it works. If it does, your Huawei is unlocked, which is good. If not, you’ll need to unlock it first from your previous carrier, because a locked phone won’t accept GLOBE SIM activation properly. Another point to note: If you’re transferring a GLOBE SIM from an old phone to your new Huawei, make sure the old SIM is already registered under your name – GLOBE requires all SIMs to be registered per the Philippine SIM Registration Act. If you haven’t registered it yet, you need to do that first via the GLOBE website or app before activating. That’s a common mistake people make – they skip registration and wonder why activation fails. Let’s add another check: Update your Huawei’s software. Outdated EMUI or HarmonyOS versions can cause compatibility issues with GLOBE’s activation protocols. For example, How to Activate GLOBE sim on Huawei Phone Huawei phones running EMUI 10 or below might have trouble with some USSD codes, so updating to EMUI 12 or HarmonyOS 2+ will make the process smoother. You can update your phone by going to Settings > System & Updates > Software Update. Taking these pre-steps will save you a lot of time later – I’ve seen friends skip these and spend hours troubleshooting instead of activating their SIM in 5 minutes.
Basic Activation Methods: USSD Code and SMS (The Fastest Ways)
Once you’re prepped, the easiest ways to activate your GLOBE SIM on Huawei are via USSD codes or SMS. These are free, no app needed, and work on almost all Huawei models. Let’s start with USSD, which is my go-to method. First, open the Phone app on your Huawei – it’s the green icon with a phone receiver, usually on the home screen. Then dial *143# and press the call button. This will pull up GLOBE’s main menu. Now, you need to navigate to the activation option. Wait, when you dial *143#, a menu pops up with numbers for different services. For activation, you’ll usually select option 1 (for My Account), then option 8 (for SIM Activation), or sometimes directly look for “Activate SIM” in the menu. But there’s a direct USSD code for activating a new GLOBE prepaid SIM: *105#. Let’s test this with an example: My neighbor Lito in Cebu got a new GLOBE prepaid SIM for his Huawei Y7a. He inserted the SIM, turned on his phone, opened the Phone app, dialed *105#, and pressed call. A few seconds later, a message popped up saying “SIM activation in progress. Please wait.” After about 30 seconds, he got a confirmation text: “Your GLOBE SIM is now active! You can start calling, texting, and using data.” That’s it – super fast. What about SMS activation? If USSD doesn’t work (maybe due to network issues), you can send an SMS to 9555 with the word “ACTIVATE” followed by your 10-digit SIM number. Where do you find the SIM number? It’s on the SIM card itself, or from the SIM pack. For example, if your SIM number is 9171234567, you send an SMS to 9555: ACTIVATE 9171234567. Then wait for a reply – usually within 1 minute, it will tell you if the activation is successful. But here’s a tip: Make sure you send the SMS from the Huawei phone that has the GLOBE SIM inserted, not another phone. Another thing: If you’re activating a postpaid SIM, the process is similar but requires more steps. Postpaid activation usually needs your account number or reference number that GLOBE gave you when you signed up. For example, if you got a postpaid plan, GLOBE will send you a reference number via email or SMS – you’ll need to include that in the USSD or SMS. My friend Ana in Davao tried activating her postpaid GLOBE SIM on her Huawei Mate 40 Pro. She first used *105# but got an error, so she switched to SMS: she sent “ACTIVATE POSTPAID [her account number]” to 9555, and that worked. Wait, but postpaid SIMs take longer to activate – usually 1-2 hours – so don’t panic if it’s not working immediately. Also, during activation, your phone might ask for the SIM PIN – enter the default PIN (1234) or the one you set earlier, and that should complete the process. A common mistake with USSD: If you get a message saying “Invalid USSD response”, it’s usually because you have no signal, or you dialed the wrong code. Double-check the code – for prepaid, *105# is correct; for postpaid, sometimes it’s *143# then option 2 (Postpaid) then option 5 (Activate SIM). If you just transferred a GLOBE SIM from another phone, inserting it into your Huawei might require re-activating it because the phone change can trigger a network reset. In that case, using *105# again will work.
Advanced Activation via GLOBE One App: For When Basic Methods Fall Short
Sometimes, the USSD or SMS methods don’t work – maybe you’re in a remote area with weak signal, or your SIM has registration issues that need a more hands-on approach. That’s where the GLOBE One app comes in, and since Huawei phones use AppGallery instead of Google Play, I’ll walk you through how to download it specifically for your device. First, open the AppGallery on your Huawei phone – it’s the default app store, usually on the home screen. Tap the search bar at the top, type “GLOBE One”, and hit search. The official app will have the GLOBE logo; tap “Install” to download it. Once it’s installed, open the app. The first time you launch it, it will ask for permissions – allow access to your SMS, phone, and storage, as these are needed to detect your SIM and activate it. Next, you’ll see a screen where you need to enter your GLOBE mobile number (the one you’re trying to activate). Make sure this number is the one with the SIM inserted in your Huawei device. Tap “Next”, and the app will send a 6-digit OTP to that number. Enter the OTP in the app, and wait a few seconds. If your SIM is already registered with GLOBE, the app will automatically detect it and prompt you to activate it. For example, my friend Carlos in Baguio had trouble activating his new GLOBE SIM on his Huawei Nova 11i – he tried *105# three times and got “Network error” each time, probably because the mountain area had poor 2G signal. So he used the GLOBE One app instead. After entering his number and OTP, the app showed a button that said “Activate SIM” – he tapped it, and within 2 minutes, he got a confirmation SMS that his SIM was active. What if the app still doesn’t work? Maybe your SIM isn’t registered yet. The GLOBE One app will also have a section for SIM registration – if you haven’t completed the mandatory registration (per Philippine law), you’ll need to do that first. Tap “Register SIM” in the app, enter your full name, ID type (like driver’s license or passport), ID number, and birthday, then follow the prompts to submit. Once registration is done, go back to the activation step. Another thing: If you’re activating a postpaid plan, the app will ask for your account reference number, which GLOBE sent you when you signed up. Just enter that number when prompted, and the app will link your plan to your Huawei’s SIM. A pro tip: If you have multiple GLOBE numbers, you can add them all to the GLOBE One app, making it easy to manage activation and services for each. For Huawei users, the app is more reliable than USSD in areas with weak signal because it uses data (if available) to connect to GLOBE’s servers, instead of relying on basic SMS or USSD. Also, if you can’t find GLOBE One in AppGallery, you can download the official APK from GLOBE’s website, but make sure to allow installation from unknown sources in your Huawei settings (Settings > Security > Unknown Sources) – only do this for trusted apps to avoid security risks.
Post-Activation Checks: Confirm Success and Fix Common Glitches
Once you’ve done the activation step, you need to make sure everything works as expected – there’s nothing worse than thinking your SIM is active only to find out you can’t call or use data. Let’s go through the checks step by step, with specific steps for Huawei phones. First, check for signal: Look at the top of your Huawei screen – you should see the GLOBE logo and signal bars (usually 1-5 bars). If you see “No Service” or “Searching”, that’s a problem, and we’ll fix that in the next section. Next, test calls: Open the Phone app, dial a friend’s number (like 9171234567) and press call. If it rings and connects, that’s a good sign. If it says “Call failed”, double-check that you entered the number correctly, or that your SIM is activated. Then test SMS: Open the Messages app, send a text to another number. If it sends, great. If not, maybe your SMS service is not activated – but usually, that’s part of the SIM activation. Now, check data connectivity: This is especially important for Huawei users, since data settings can sometimes be off. Open your browser (like Huawei Browser, which is pre-installed) and go to google.com. If the page loads, data is working. If not, you need to check your APN settings – this is a common issue with Huawei phones after activation. Let’s walk through that: Go to Settings > Mobile Network > Access Point Names (APN). You’ll see a list of APNs – if you don’t have a GLOBE APN, tap the + sign at the top right to add a new one. Name the APN “GLOBE”, set the APN field to “internet.globe.com.ph”, the username to “globe”, password to “globe”. Leave other fields as default (like MMS proxy, etc., unless you know what you’re doing). Tap “Save”, then select the GLOBE APN you just created. Now, turn off mobile data and turn it back on – wait 10 seconds, then try loading Google again. For example, my cousin Pedro in Iloilo activated his GLOBE SIM on his Huawei P30 Lite, but data wasn’t working. He followed these APN steps, and it started working immediately. Another post-activation check: Load your prepaid balance. If you have a prepaid SIM, you need to load credits to make calls or use data. You can do this via the GLOBE One app, or by buying a load card and scratching it to get the PIN, then dialing *143# and selecting “Load” to enter the PIN. If you’re postpaid, you’ll get a monthly bill, so no need to load, but make sure your payment method is set up in the GLOBE One app to avoid service interruptions. Also, check if your roaming is activated if you’re abroad – if you’re using your Huawei phone outside the Philippines, you need to activate roaming separately via GLOBE’s app or USSD *143# then option 3 (Roaming). That’s an extra step after initial activation. If all checks pass, you’re good to go! But if something is off, don’t worry – most issues are easy to fix. For dual-SIM Huawei users (like Huawei P Smart 2021), make sure the GLOBE SIM is inserted in the primary SIM slot – some Huawei models only support activation in the first slot. That’s a common mistake for people with two SIMs, and it can cause activation failures.

Troubleshooting Persistent Activation Errors: When All Methods Fail
Even if you follow all the steps, sometimes you’ll hit a roadblock – don’t panic, most errors have simple fixes. Let’s go through the most common errors for Huawei users and how to solve them. First error: “SIM not detected” or “Invalid SIM”. This usually means your Huawei phone isn’t reading the SIM card properly. Let’s fix this: Turn off your Huawei phone completely, remove the SIM tray (use the SIM eject tool that came with your phone, or a paperclip if you don’t have one), take out the SIM card. Use a soft, dry cloth to gently wipe the gold metal pins on the back of the SIM – sometimes dust or oil from your fingers blocks the connection. Reinsert the SIM card firmly into the tray, push the tray back into the phone, then turn on the phone. If that doesn’t work, try another GLOBE SIM – maybe your current SIM is damaged. Second error: “Activation failed due to invalid ID”. This happens if you haven’t completed the mandatory SIM registration required by Philippine law. To fix this, go to the GLOBE website (globe.com.ph/simreg) or the GLOBE One app, enter your details correctly, and submit a valid ID (like a driver’s license, passport, or UMID card). Wait for the confirmation SMS from GLOBE saying your registration is approved, then try activating again. Third error: “No network service” after activation. As I mentioned earlier, check your APN settings, but also make sure airplane mode is off (swipe down from the top of your screen to open the quick settings panel – tap the airplane icon to turn it off if it’s blue). Toggle mobile network off and on the same way – tap the mobile data icon to turn it off, wait 5 seconds, then turn it back on. If you’re in an area with very weak signal, move to a higher ground or near a window – signal strength improves in open spaces. Fourth error: USSD codes not working on Huawei. Huawei phones sometimes have restrictions on USSD codes for security, especially if you have a custom ROM or modified software. If that’s the case, switch to the SMS or GLOBE One app method, which is more reliable. Another common error for Huawei: Error codes like 012 or 015 during activation. Write these codes down and tell the support agent – error code 012 usually means your SIM is not yet registered in GLOBE’s system, so the agent can check your registration status and fix it immediately. If none of these fixes work, the best step is to contact GLOBE’s customer support. For Huawei users, you can do this via the GLOBE One app (go to Help & Support), or call 211 from your GLOBE SIM (it’s free). When you call, have your SIM number, Huawei phone model, and error message ready – this will help the support team assist you faster. For example, my friend Maria (the same one from the basement) had another issue: after activating her SIM, she couldn’t send texts. She tried all the fixes, then called 211, and the support agent found that her SMS service was not provisioned correctly, and fixed it in 5 minutes. Another tip: If you’re transferring a GLOBE SIM from an old Huawei phone to a new one, sometimes the activation needs to be re-triggered. Just insert the SIM into the new phone, dial *105# again, and that should refresh the activation. If you’re using a Huawei phone that’s been locked to a different carrier, you’ll need to get it unlocked before inserting a GLOBE SIM – a locked phone will show “Invalid SIM” even if you have a valid card, so this step is crucial. I had a classmate in college who bought a second-hand Huawei phone locked to Smart, and he spent 2 days trying to activate GLOBE SIM before he realized it was locked – after unlocking, it worked in 2 minutes. If you follow all these troubleshooting steps, you should be able to activate your GLOBE SIM on your Huawei phone without any major issues. Remember, patience is key – sometimes activation takes a few minutes, especially for postpaid plans, so don’t rush to do multiple activations at once, as that can cause errors.
