Nextel push to talk headset code#

The phone is one of the most rugged on the market, and there are reports that you can use them to hammer in nails, so useful if you're out in the sticks. The PTT is on the side of the phone like a 446 rig, and you must wait for three short 'beeps' BEFORE talking, or you'll miss the first second of an over.Ī useful feature is the fact that if there's no-one in range, or they're switched off, the i355 will let you know on screen, and also audibly with a 'fart' The downside is that the reception is digital, so you either get all the message or none!īeing primarily a phone, the i355 will vibrate (if set), or bleep to indicate someone calling you.Īnother thing to remember is that there's a slight (0.3 second) delay, where the phone will receive/decode what it hears, before 'playing' it to you, and if you are near the person you're speaking to, you get an echo effect which is quite amusing. They FAR and AWAY beat the crap out of PMR446 radios, and being digital, it is like being in the ame room as the person you're talking to.

The i355's have an output of 1/2 a watt in the 902-928MHz range, and you'd be amazed at what distance you can get with that power.

In effect, they change channel, hundreds of times a second, and the code you both enter, keeps the rigs syncronised with each other, so you just get uninterrupted crystal-clear transmissions with no chance of being heard by anyone you don't want 'wigging' on the side

The secret is that these rigs operate in the USA allocated ISM 'free' band which is 902-928MHz, and just to ensure that privacy is maintained, the transmissions are entirely digital (actually data as opposed to analogue voice).Īnd the icing on the cake is that's not all, because the i355's use military style frequency hopping, right across the 26MHz band available!!! The chances of anyone else in UK having the same channel and code as you is highly unlikely, and anyway, you can put your own code (use your phone number, and save it as default, or any number from 10 - 10,000,000+, and the i355 will only be heard by your intended recipient and will not be heard by anyone else (including GCHQ!!). When you are all set up and ready to go with these babies, they are the best and most private way to talk to your buddies there is! Your O2 or Vodafone SIM WILL NOT WORK!, and you'll just get a screen message asking for the code number, which is not available! I've heard that Virgin SIMs will work, but I don't know whether this is true or not, and honestly, it would be unwise to try! It doesn't matter whether the SIM is old and deactivated or new and current, cos you won't be making calls on network anyway, but without it, you have a dead paperweight! I bought these only withthe proviso that the seller included an old SIM with them. The IMPORTANT thing to remember if you want to buy these, is to ensure that you get a NEXTEL SIM card included with each 'rig'!Īlthough you won't be actually using any network (they wouldn't work in the UK anyhow - different to GSM), the i355 will not even go into the 'Direct-talk' (back to back) mode without the NEXTEL SIM.

I actually bought 3 of these Motorola i355's on Fleabay - 2nd hand from USA.
