VPN for International SIM Cards

VPN for International SIM Cards

Is OneSimCard’s mobile roaming secure?

Yes, OneSimCard works only with licensed and reputable mobile carriers like AT&T ,Vodafone, Claro and others to provide you with secure data roaming around the world.  All of your OneSimCard communications whether it is calling, texting or browsing the web use protected connection with cellular towers.

Why use a VPN?

Connecting to the internet via cell tower is not the same as connecting over open Wi-Fi, where your communications are the most vulnerable for interception. Basically, anyone with a Wi-Fi enabled laptop can be a hacker. This is where VPN can be helpful.

VPN, or Virtual Private Network, allows you to set up a private, secure connection to another network, often in another country. This makes it appear as if you were browsing from that country, while also creating an encrypted tunnel for your data so it can’t be intercepted by snoopers, hackers and third parties.

Initially created by Microsoft in the mid-nineties as a way for employees to remotely and safely access their office network. VPN works with regular secure data roaming as well as protected and unprotected Wi-Fi connections.

Do I need extra VPN protection with international SIM card?

VPN has its pros and cons. VPN quality can vary significantly from provider to provider. Common VPN issues include: 

  • A slower or unreliable internet connection
  • Specific blockades of VPN services (for example by Netflix)
  • Unknown encryption strength
  • The logging and potential reselling of your internet habits to third parties
  • An unwarranted sense of complete online privacy
  • Free VPNs can be worse than none at all

In some countries, like Russia and China, you can only use government-approved VPNs. In addition, access to certain internet resources like social media sites and search engines can be limited or unavailable. Using cellular data directly (without VPN) sometimes can help bypass such censorship.  

So although it is possible to use VPN with your mobile roaming, in reality you may choose not to. Unless you are 100% sure about your VPN service provider, in some situations, you may be better off without it.

When using OneSimCard, with or without VPN, you can rest assured that your communications are protected by industry standard security protocols anywhere you go.
