FREQUENTLY ASKED QUESTIONS

SMS messaging usually works without any additional setup of the phone.
In rare cases when there are issues sending or receiving text messages, please look at the following:

Problem with Sending SMS:

• Incorrect SMSC number (SMS Service Center Address) in handset settings.

SMSC number should be set as follows:

1. For Standard  and Plus OneSimCard SIM: +3725099000 for all countries except:

a. China:  +85290296747

2. For the Expedition (former Data & Roam) SIM as well as for Europe & More SIM: +37256100041

Special instructions for Apple Phones:

With Apple iPhones to check SMSC:

From the phone dialer Dial *#5005*7672# 

You will see the SMSC set currently on the phone. 

To change the SMSC on Iphone dial: 

Plus and Standard SIMs: **5005*7672*+3725099000# for all countries except China and **5005*7672*+85290296747# if in China.

Expedition (formerly Data & Roam) and Europe & More SIMs in any country: **5005*7672*+37256100041#

• NOTE: It is important to have the "+" symbol entered in front of the SMSC number.
• You can find locations of the Message Settings menus for different phone models here.

If your phone requires the name of Message Center Name enter: SMSC
SMS lifetime is short - must be at least 2 hours or set to Maximum settings.
Try sending SMS from OneSimCard menu

 Problem with Receiving SMS:

• Receiving Handset does not have enough free memory for incoming SMS.
• Receiving Handset was turned off or out of the coverage area during SMS lifetime set on the sending phone - usually 2 hours.
• Sender's SMS provider does not have an agreement with the receiving network.

Note: You can always dial 00 instead of + when making outgoing calls. For example, to reach OneSimCard customer service in the USA you can just dial 001 617 3138888.

You should consult the phone manual for this info. Different manufacturers have specific ways to access the '+' key, so make sure you know yours.

Here are few known ways:

• Bosch: Press and hold the star (*) key until the "+" sign appears.
• Motorola: Press and hold the zero key until the "+" sign appears.
• Nokia: Press the star (*) key twice in rapid succession.
• Pocket PC: Pull up the keyboard, hit the <123> button in the top left corner, and select "+" from the resulting screen.
• Samsung: Press and hold the zero key until the "+" sign appears.
• Sony Ericsson: Press and hold the zero key until the "+" sign appears.
• Treo 270: Press the blue button and then the "G" key.

The  eSIM World, eSIM Asiania, OneSimCard Europe & More and Universal SIM cards do not use the callback to make an outgoing call in over 70 countries.

Currently, the mobile application to remove the callback on other SIM cards is not available.

There are two ways for SMS message to be sent:

• From the OneSimCard application menu called OneSimCard - TravelSMS. To send the message, you need to locate OneSimCard menu on the phone and then scroll down to TravelSMS menu. Sending text message this way is the least expensive and will cost you 15 cents per message from any country.
• Usual way from SMS sending menu of the phone. It cost 40 cents per text message from most countries with the exception of few countries where the rates are higher.
  Find detailed rate information here.

Bear in mind that sending SMS messages to the abbreviated special SMS destinations like voting, music downloads, etc. will cost you $9.00 per message.

This does not apply to DataMax SIM cards.

The OneSimCard phone number has no expiration, provided you made at least 1 call or sent an SMS once every 12 months.

However, the funds on the SIM expire 10 months after your last recharge. The minimum recharge amount is $25. You can keep the balance from expiring by simply recharging at least once every 10 months. If you let your balance expire, then all you need to do to get the service up and running again is to log in and add funds to your SIM card. Automatic recharge will be canceled if you let your funds expire.

NOTE: For Physical 3-in-1 DataMax & DataMax eSIM SIM cards, if the SIM card has no balance, the SIM will expire and be removed from the account after 7 days, unless there is a data package currently active on the SIM (not a future activation). If there is no balance on the SIM and the active data package expires, the SIM will expire 7 days following the expiration of the active data package.

An expired SIM can be restored for a $10.00 restoration fee plus a recharge of at least $25.00.

Each mobile data session is charged for a minimum of 10kB usage. Even if you check just one 3k email you will be charged for 10kB of usage. In some countries this can be over 30¢ per session, however in Europe and elsewhere it can be as little as 1¢. Check all rates.

Please note: Some phones, like iPhones, Androids, and other smartphones, can access data without you even knowing it if you have data enabled. We strongly recommend checking the settings on your phone and disable mobile data roaming if you will not be needing data service. By default, all SIM cards are pre-programmed with data service enabled, once you activate your data package.
