CARING FOR YOUR PHONE

MAKING IT LAST

Your phone is a complex electronic device; 

think of it as a mini-computer. Here are 

some hints that should help you extend the 

life of your new phone.

Store your phone in a protective case. 

The touch screen of your phone is delicate 

and should be protected from scratches.
Phones aren’t cheap, so keep yours in a 

safe place—away from children who may 

find it fun to see if the phone sinks or floats, 

and away from dogs that find plastic-coated 

products to be irresistible chew toys.
Water will damage your phone and 

accessories—even a small amount such as 

water droplets from a soda in your car  

cup-holder, melting snowflakes, tears of joy, 

squirt-gun crossfire or steam from hot water 

in the kitchen or bathroom.
Use only batteries and accessories from 

the original manufacturer of your phone. 

Non-approved accessories can cause 

damage to you or your phone and shorten 

the phone’s life. Hint: If it’s being sold out of 

someone’s car trunk, walk away.
If your charger or any other accessory 

is damaged, replace it or take it to a 

qualified service dealer. Do not attempt 

to operate your phone charger if it has 

received a sharp blow, been dropped, 

thrown from a speeding motorcycle or is 

otherwise damaged; doing so may damage 

your phone.

TIPS FOR SAFETY

Check with your doctor if you have a 

pacemaker or hearing aid in order to 

ensure that cell phone usage is safe with 

your phone. If you have questions about 

the interaction of cellular radio frequency 

and any other electronic equipment, ask 

the manufacturer of the equipment if cell 

phone radio frequencies will disrupt the 

equipment’s performance.

When you are driving, T-Mobile 

encourages you to use your phone in 

a safe and sensible manner. Here are 

a few tips:

n

  Assess road conditions before 

answering. Your safety is more 

important than any call.

n

  Prepare your hands-free headset, 

if you have one, or turn on your 

speakerphone option before you  

start moving.

n

  Keep your phone close. If it rings 

and you discover it’s in the back 

seat, do NOT crawl over the seat 

to answer it while driving.
