Understanding data roaming<br />

If you looked at your phone settings, you may have come<br />

across a setting called ‘data roaming’. Enabling it would<br />

bring a pop-up message saying that turning this option on<br />

may incur significant network charges.<br />

So, what is data roaming, and why would you enable it<br />

if it could incur these charges?<br />

Roaming<br />

Roaming is when your phone leaves the range of your<br />

network and loses its signal. This goes a little further than<br />

simply going into rural parts of the country; it means<br />

leaving the country altogether. When you are in a country<br />

that is out of range of your network provider’s territory,<br />

your phone is now roaming. Data roaming, therefore, is the<br />

act of getting data while outside of your network’s range.<br />

How data roaming works<br />

Let’s say you are a Nigerian and a customer of 9Mobile<br />

who provides you with a phone signal and 4G data. You<br />

feel like taking a holiday, so you decide to jet off to sunny<br />

Spain for a bit. While you are there, you would still like to<br />

catch up on your YouTube videos and podcasts while you<br />

are on the beach, so you take your phone with you.<br />

There is a problem, however; 9Mobile doesn’t have a<br />

presence in Spain. Therefore, if you left for Spain, you<br />

would be stuck without a phone signal. If you had an<br />

unlocked phone, you could exchange the SIM card with a<br />

Spanish provider to get data there. But what if your phone<br />

was locked to 9Mobile and you can’t change the SIM?<br />

In order to tackle this problem and help their customers<br />

get a signal no matter where they are, 9Mobile struck a deal<br />

with the Spanish network so that if any of their customers<br />

goes to Spain and wants to use 4G or make a call or text,<br />

the Spanish network would pick up the slack and give them<br />

a network signal, despite the fact that the customer is a<br />

9Mobile user. In return, 9Mobile will support any Spanish<br />

network customer coming from Spain.<br />

The result<br />

Now when you take that flight to Spain, you can use the<br />

Spanish network signal to get 4G; however, there is a good<br />

chance that additional charges for using a foreign network<br />

will come into play.<br />

To prevent itself from accidentally racking up a huge<br />

phone bill, your phone won’t automatically connect to the<br />

Spanish network when you arrive. You have to manually<br />

tell your phone to connect by enabling data roaming. Once<br />

done, you can now enjoy 4G abroad without changing<br />

SIM cards.<br />

When you arrive at Spain with roaming enabled, you<br />

wll see that your network provider’s name will change<br />

404 error<br />

404 Error Code is caused in one way or another by<br />

misconfigured system files in your windows operating<br />

system.<br />

It is a common website error message that indicates<br />

a webpage cannot be found. It may be produced when a<br />

user clicks an outdated (or ‘broken’) link or when a URL<br />

is typed incorrectly in a web browser’s address field. Some<br />

websites display custom 404 error pages, which may<br />

look similar to other pages on the site. Other websites<br />

simply display the web server’s default error message<br />

text, which typically begins with ‘Not Found’. Regardless<br />

of the appearance, a 404 error means the server is up<br />

and running, but the webpage or path to the webpage is<br />

not valid.<br />

So why call it a “404 error” instead of simply a “Missing<br />

Webpage Error?” The reason is that 404 is an error<br />

code produced by the Web server when it cannot find a<br />

webpage. This error code is recognised by search engines,<br />

which helps prevent search engine crawlers from indexing<br />

bad URLs. 404 errors can also be read by Web scripts and<br />

website monitoring tools, which can help webmasters<br />

to something like ‘España Móvil (9Mobile)’. This just<br />

means you are currently using España Móvil’s network as<br />

a 9Mobile customer.<br />

If you travelled with a friend and they used a different<br />

network, they may see a different Spanish name pop-up<br />

locate and fix broken links.<br />

Other common Web server codes are 200, which means<br />

a webpage has been found, and 301, which indicates a file<br />

has moved to a new location. Like 404 errors, these status<br />

messages are not seen directly by users, but they are used<br />

by search engines and website monitoring software.<br />

There are two ways to fix 404 error:<br />

Advanced computer user solution (manual restore):<br />

• Start your computer and log on as an administrator.<br />

• Click the ‘Start’ button then select the following- All<br />

Programs, Accessories, System Tools, and then click<br />

System Restore.<br />

In the new window, select “Restore my computer to<br />

an earlier time” option and then click Next.<br />

Select the most recent system restore point from the<br />

“On this list, click a restore point” list, and then click Next.<br />

• Click Next on the confirmation window.<br />

• Restarts the computer when the restoration is finished.<br />

Novice computer user solution (completely automated):<br />

• Download (Error 404) repair utility.<br />

• Install program and click Scan button.<br />

• Click the Fix Errors button when scan is completed.<br />

•Restart your computer<br />

corresponding to the network their provider struck a deal<br />

with.<br />

Significant charges<br />

While roaming is very useful, it can come at a hefty<br />

additional cost to your base data and call rates. This is what<br />

the pop-up is warning you about when you enable data<br />

roaming. Different network providers will have different<br />

charges depending on which country you visit, so be sure to<br />

check up the stated charges on the website before travelling.<br />

In order to find these charges, you don’t have to find<br />

out what network you’ll be switching to when you arrive<br />

at your destination. Simply search for the one you use at<br />

home and look up their roaming charges, and it will apply<br />

when you go abroad, even after the network changes. Just<br />

be sure you select the correct country, as charges can differ<br />

depending on where you go.<br />

If you are lucky, you may find there are no roaming<br />

charges at all. For example, if you are in Europe, you will<br />

be pleased to know that the European Union scrapped<br />

roaming charges for travelling within its boundaries, so<br />

you can go from France to Italy without worrying about<br />

roaming costs at all.<br />

Effect on WiFi<br />

Roaming charges won’t affect any WiFi connections<br />

you access during your stay. If your hotel has WiFi, or you<br />

find a café with a hotspot, you can use that at its advertised<br />

cost (if any) without paying anything extra. Roaming only<br />

comes into play when you are using a cellular network<br />

(like 4G) abroad.
