Let’s help you restore your Smart SIM’s roaming service — fast.
Why Smart Roaming Issues Happen
Roaming depends on a combination of your phone settings, Smart’s partner networks in the country you’re visiting, and your account’s roaming status. A single mismatch can break roaming temporarily.
Here are the typical causes:
- Roaming was not activated before leaving the Philippines
- Your phone is locked to a local PH network
- Your SIM is old and not LTE- or 5G-ready
- Incorrect network mode (e.g., 5G-only in a country with limited 5G coverage)
- Insufficient balance for roaming services
- Partner network issues in the country you’re in
- Smart temporarily blocked your SIM for security verification
- Your account requires OTP verification but you cannot receive OTP abroad
Now let’s solve them one by one.
Issue #1: No Signal or “Emergency Calls Only”
This is the most common problem Smart customers experience when landing in another country. It usually means your device cannot connect to a roaming partner network.
How to Fix:
1. Enable Data Roaming
On your phone:
iPhone:
Settings → Cellular → Cellular Data Options → Enable Data Roaming
Android:
Settings → Connections → Mobile Networks → Data Roaming
2. Switch Network Mode
Some countries have weak 5G coverage. Switching modes helps your SIM connect automatically.
Try this sequence:
- 5G/4G/3G/2G (Auto)
- 4G/3G/2G (Auto)
3. Manually Select a Network
Turn OFF automatic network selection and try choosing networks manually.
Typical roaming partners: Globe, Vodafone, AT&T, SoftBank, Telstra, etc. (Varies by country.)
4. Restart Your Phone
A simple reboot often triggers the SIM to re-register to a new network.
5. Reseat the SIM Card
Remove the SIM card and insert it again. For eSIM users, toggle the eSIM OFF then ON.
Issue #2: Cannot Receive OTP (Most Common for OFWs)
Many travelers face this issue, especially when verifying banking apps, GCash, or Smart services. Smart roaming allows receiving SMS even without a data pack — but not if the SIM isn’t properly registered or roaming isn’t active.
How to Fix:
1. Make sure your Smart SIM is still active
Inactive SIMs will not receive messages abroad. You must top-up at least once every 365 days.
2. Check if SMS roaming is enabled
SMS roaming works even without load — but the SIM must be in Home Mode before leaving the Philippines. If not, you’ll need assistance from Smart (details below).
3. Try switching networks
Some foreign networks block inbound SMS from Philippine numbers. Try switching to another roaming partner in the manual network list.
4. Turn Airplane Mode ON for 10 seconds
This refreshes the network connection and can trigger pending messages.
5. Clear your inbox
Low phone storage or full inbox can prevent new OTP messages from arriving.
6. Disable 5G temporarily
OTP delays sometimes happen on unstable 5G roaming signals.
Issue #3: Mobile Data Roaming Not Working
Even if you have good signal, data roaming may still fail due to APN issues or incorrect phone settings.
How to Fix:
1. Turn ON Mobile Data + Data Roaming
Both must be enabled for roaming data to work.
2. Check APN Settings
Your APN must be:
APN: internet Username: (leave blank) Password: (leave blank)
3. Restart your phone after buying a roaming package
This helps Smart register your data entitlement to the partner network.
Issue #4: “Roaming Not Activated” Notification
If you suddenly lose service or receive this notification, Smart may have disabled roaming due to activity review or a technical glitch.
Solution:
- Turn phone off for 2 minutes
- Turn it back on
- Connect to a different network
If that doesn’t work, contact Smart support.
Before Traveling: Smart Roaming Checklist
To avoid roaming issues altogether, do these BEFORE leaving the Philippines:
- Enable roaming in the Smart App or by texting ROAM ON to 333
- Load at least PHP 100 for emergency SMS
- Update your SIM to LTE or 5G
- Take note of Smart’s hotline numbers abroad
- Switch off airplane mode upon landing and wait 2–3 minutes
