Data Was Working but Suddenly Stopped

When Data Stops Out of Nowhere

This is a frustrating situation. Everything was working — you were browsing, navigating, messaging — and then suddenly, nothing. No data.

The good news is that when data was working and then stops, the list of possible causes is narrower than when it never worked at all. Something specific changed, and we can usually track it down.

Check 1: Your Data Allowance May Be Exhausted

This is the most common reason data stops mid-trip. You might have used more data than you realized — especially if you were streaming video, making video calls, or downloading large files.

1. Go to onlyesim.com and log into your account
2. Check your active plan's remaining data balance
3. If it's at zero, that's your answer

What to do: Purchase a top-up or a new plan for your destination. Once activated, data will resume.

Check 2: Your Plan Validity May Have Expired

Every eSIM plan has two limits: a data cap and a validity window. Even if you still have data remaining, the plan won't work past its expiration date.

For example, a plan might offer 5 GB valid for 7 days. If you only used 2 GB but the 7 days are up, the plan has expired regardless.

Check your plan's validity dates in your account dashboard. If the plan has expired, you'll need to purchase a new one.

Check 3: Temporary Network Congestion

Networks get congested, especially in busy urban areas or during peak hours. If the network is overloaded, your data connection might drop temporarily.

What to try:

• Wait a few minutes and try again
• Move to a slightly different location
• Manually select a different carrier in your network settings

If data comes back on its own after a few minutes, congestion was likely the issue.

Check 4: Your Phone Settings May Have Changed

It's surprisingly easy for settings to change without you noticing — an iOS update, accidentally toggling a setting, or a phone restart that reset defaults.

Check all of the following:

• eSIM is still the default data line: Go to your Cellular/SIM settings and confirm the eSIM is selected for mobile data. If your physical SIM took over as the default, data would stop flowing through the eSIM.
• Data Roaming is still ON: A phone restart or software update can sometimes reset this. Verify it's still enabled for your eSIM plan.
• The eSIM line is still turned on: Make sure the eSIM hasn't been accidentally disabled.

Check 5: SIM Conflict

If you recently changed your physical SIM settings — swapped in a new SIM card, changed your home plan, or adjusted dual-SIM settings — it can affect your eSIM's data connection.

What to check:

• Confirm your eSIM is still set as the active data line (not your physical SIM)
• If you inserted a new physical SIM, go to your Cellular/SIM settings and re-select the eSIM for data
• Try disabling the physical SIM temporarily to see if the eSIM connects on its own

If data works fine with the physical SIM disabled, there's a conflict between the two that needs to be resolved in your dual-SIM settings.

Quick Recovery Steps

If you've confirmed your plan is active and has data remaining, run through this quick recovery sequence:

1. Toggle Airplane Mode on for 30 seconds, then off
2. Restart your phone if Airplane Mode didn't help
3. Manually select a network if the phone isn't reconnecting automatically
4. Re-enable Data Roaming if it got turned off

Most of the time, one of these steps will restore your connection.

If your plan is active with data remaining and none of the steps above fix the issue, something may have changed at the network level. Contact our support team with your order number and we'll investigate on our end.
