Comment on Free mobile calls via Wi-Fi by imcellular

Since your phone has Wi-Fi access, then you can use access to Wi-Fi networks (where available) to reduce your bill in many ways (please read the articles to see how), bincluding (a) avoiding data charges by using Wi-Fi (often free) instead of your 3G/4G data plan, and (b) avoiding roaming costs for voice and data. So, YES, you can make incoming and outgoing calls.

To make low- or no-cost Voice calls over Wi-Fi, you will need an app on your phone that allows you to call over the Internet (VoIP software). I recommend Skype, if you do not already have this on your phone (some carriers, such as T-Mobile, include it in their smartphones.

The “Mobile Wi-Fi” feature that your phone has is a more advanced feature than just Wi-Fi access. Mobile Wi-Fi allows your phone to create a Wi-Fi hotspot, to share data access with other Wi-Fi devices (iPad, laptop, etc.), carrying this data your 3G data plan. You do not need this feature to use Wi-Fi to save money. In fact, sharing your 3G data plan with others can be very costly, depending on your plan–so be sure that you know your data plan limits before you use this feature, and avoid using it when roaming, as the costs can be devastating.

I have a mobile wi-fi (Mi wifi). 1. Can I make free calls if I connect my smartphone to this hot spot? 2.What about incoming calls?

Yes! Just purchase the SIM from a major carrier that serves the locations where you will be travelling.

Although there is no T-Mobile store in Heathrow (see Heathrow Store Finder), she can Top Up at many other location, including a nearby T-Mobile store. Find a store using the T-Mobile Store Finder (for the UK) at http://www.t-mobile.co.uk/store-finder/ You may also top up at Tobacconist or other stores that sell Top Up (scratch off) cards.

YES, to lower your cost when traveling internationally, your best value is to buy services from the local (in-country) provider (unfortunately, as this is inconvenient). This is especially true for mobile data. Roaming costs for mobile data can be 1000X higher than the cost of obtaining them from the local provider. To determine which plan is best for you, review the plans before you get there and select the one that best fits your needs. For example, if you need occasional Internet access (to download a book or check your email), then buy a plan with a small amount of data. Alternatively, if you will be working furiously and need ongoing Internet access, then you may wish to buy a plan with a large allocation of data (e.g., 2 GB) for a fixed cost.

I have a BlackBerry Torch using Vodacom in South Africa & will be visiting the UK for 2 weeks. I plan to purchase a Vodafone sim card in UK. Will I have access to the BlackBerry Services eg unlimited internet. What are the cost implications?.
