Dual SIM phones aren’t exactly common in the US. While there are some, most phones sold are of the single SIM variety, and in most cases are typically locked to a particular carrier. However what if you wanted an unlocked phone to take with you to a different country where you could insert a SIM card? What if you still wanted to receive calls or text messages from your original number? Well that’s where a dual SIM phone will come in handy, but if you didn’t want to get another phone, perhaps the Teleza could be the answer to your problems.
