ThimphuTech was the first technology blog in Bhutan. We started writing it in 2009, just as broadband and mobile internet started to take off. (Although internet in Bhutan was launched in 1999, it was either super-slow or super-expensive, and was only used by a selected few).

In the blog, we wrote about technology and food, but also about plenty of other stuff. The blog became popular and influential in Bhutan. A companion bi-weekly column -- Ask Boaz -- was published for many years in the Kuensel, Bhutan's national newspaper. (The complete Kuensel columns are available as an ebook, Blogging with Dragons).

We stopped updating the blog when we left Bhutan in 2014, but the information within the posts can still prove useful, and thus we decided to keep it online.

We thank all our readers.

Will the new iPhone 5 work in Bhutan?

"I need it, and I need it NOW!"

Two years ago we wrote one of our most popular posts ever, "Will the new iPhone 4 work in Bhutan?". That post still gets plenty of hits. Visitors to the Kingdom are eager to know whether they should pack their unlocked smartphone before that hair-raising landing in Paro. The answer to that question was a definite yes - one just needs to chop the B-Mobile (or TashiCell) SIM card down to the micro-SIM size.

The iPhone 5 was launched yesterday. It has a bigger and taller screen, a sharper camera, more processing power, as well support for LTE 4G, which is a high-speed data network (currently unavailable in Bhutan). One 'upgrade', however, will affect Bhutanese subscribers. The iPhone 5 uses a nano-SIM. The nano-SIM is even smaller than the micro-SIM:

In theory, one could carefully cut a SIM (or a micro-SIM) down to a nano-SIM, since the physical contact sizes are the same. Nano-SIM cutters are already selling on E-bay. However, there is a caveat: In addition to being smaller, the nano-SIM is also thinner than the previous SIMs (0.67mm compared to 0.76mm, which is about 15% less), and so there is a chance that a cut-down SIM will be too thick to fit into the iPhone slot.

Update (24/9/2012): Cut down SIMs fit the iPhone 5 tray.

As far as I know, B-Mobile and TashiCell have not put out orders for nano-SIMs. The only option left for iPhone owners is to shave off that extra 0.09mm of plastic, perhaps using sandpaper. Whether this is possible without affecting the internal circuitry remains to be seen. The best strategy is not to jump and order an iPhone 5 (yet), but wait until more information is available.
