I can connect my speakers wholeheartedly. I bought the phone through retail since it was not directly available on Amazon. My service sim and my private SIM card are housed there. The service is the main SIM card. Thus my service-SMP remains with the hybrid card in the luggage because of the Nokia 301 battery but keeps> 5 days. However, I call so just because I'm doing the rest on SMP or other devices. So from my 3 SIM cards are two housed in the same mobile phone and therefore I use mostly only the Nokia 301. Very pleasant.
Call quality is really dull, but I am satisfied so far. Speakerphone is also good but not as good as with SMP's. I buy a silicone sleeve to and available and hope the device with me for several years. Even though I have the device only for a few days, there is of me 5 stars and strong buy recommendation.
