Have you recently submerged or heavily wet your phone? Your phone has two flex cables with micro connectors that can be easily shorted by liquids. This requires disassembly and cleaning by someone with expertise. Assuming it has not been subjected to fluid contamination proceed as below.
Ask someone with a known to be operating Nextel or Boost Mobile phone to allow you to boot their phone with your SIM installed.If it boots normally, it is not your SIM. Use a sponge make up removing tip, like a Q-tip but with a sponge end, and clear alcohol to clean the SIM, as well SIM contacts in the phone, fully charge yours or use a fully charge substitute battery, and then reinstall it in your phone. If it does not power up you may be experiencing partial flex cable failure. You have to keep your phone away from devices that create magnetic fields like speakers and TVs.

You could be in a location with bad coverage/reception (few or no bars). Try moving to a location with better coverage.
You might also need to reboot your phone. Try turning it off by holding down your power button (depending on your model you might need to select "turn off" from a menu after that). Remove your battery and wait 30 seconds to a minute. Replace your battery and turn your phone back on. Wait for it to finish booting and try your call again. Hope this helps!

Firstly, unplug the base unit, then remove from this base unit the ethernet cable and most importantly, unplug the telephone line! Then remove the batteries from the 2nd handset. Keep everything unplugged for a few minutes, then plug the power into the base unit, wait 1 minute, then plug in the Ethernet cable and wait 5 more minutes. Do NOT plug in the telephone line just yet. After the 5 minute wait, put the batteries back into the 2nd handset and then follow the registration instructions from the manual (copied below)...
Make sure you have configured the language, country code, and area code of your phone before registering additional handsets.
1. Press "Reg.". Register shall be highlighted. 2. Enter the system PIN (Default: 0000). Use "Clear" to correct typing errors. 3. Press "Enter" to confirm. • Your handset starts searching for the base. 4. Press the top button on the base unit until the two indications turn off.
• If registration is unsuccessful, the signal icon displays steadily.
TIP: IF REGISTRATION FAILED, REPEAT THE ABOVE PROCEDURE.
Like other methods, you must hold down the button on the base unit until the lights STOP blinking. When you have successfully registered your 2nd handset, then plug in the telephone line into the base station. I did the above and it worked! The trick is to be patient and wait the few minutes while everything resets itself.
